I love the pace, the characters, the art, & basically everything about this!
Though I think the behavior of the old friend & his sudden interest was a bit forced, overall there isn't any nonsensical, random, out-of-character unnatural behavior in this.
I hope the ending won’t disappoint, but so far this one gets full marks from me🙂

...except for the incident where the protagonist almost gets sexually assaulted.

Otherwise, very cute story that NEVER turns batcrap insane like most longer manga. I also like the one guy’s mom who is so accepting. We need more of that.

A perfect example of a manga that uses one of the most cliche tropes (honor-ish student x delinquent) but develops it in a very unconventional way. There's a subtle development in their relationship that feels so natural and humane. Their interactions are casual at times, but you'll notice how there's affections laced in their actions and way of words as they grow closer to each other. I love how their first sexual experience together was depicted as awkward, it felt organic that way. They went through so much first times and feelings that were at first alien to them (such as jealousy and insecurities), and navigate through the ups and downs of their relationship. However, it's not like their relationship will be completely conflict-free once they've grown. The conflict and inner demons are still there, but they handle them in a more mature approach as they have applied what they've experienced during the earlier phases of their relationship.

Also, if you notice... you almost never see them professing "I love you"s to each other. Expressing love thru verbal means is equally important, for as for Chika and Natsuki, you can definitely f e e l their love through how they act with each other. These subtle things are what make me want to reread the manga for the nth time in order to identify these subtle details and muse over them.

I also love how the development in BSC is not limited to the MCs alone. Their growth definitely affects people around them (you can see this especially from one of their friends, which will be highlighted in the fifth volume). There are also some crucial issues that will be present in this manga, but the author approaches it in a very delicate way so those issues would not feel too 'sudden' or 'out of place'. Overall, this is a very well written manga that I will continue enjoying as I get older and older... Watching over all the characters in BSC really gives me joy.

Just being together, understand each other you know. And my personality is like that of the black haired glasses guy. So... I feel understood.
Update: Man! When the uke flustered as the seme thrusted it in, normal seme would lose control and hit it harder and shit, and it's not my taste. But this dude, my dude, insisted for the sake of the uke, and man that is goal. Goal. Gold!

Its warmness, its sweetness, its tenderness, its lightness...

I love everything about this story. It became one of my all-time favourite with just one read (and, of course, I have re-read all the released chapters a couple of times too).

There are not many stories like this one in yaoi. This one is so well constructed it deserves more than yaoi readers, it should be read by anyone who wants a story worth of reading.

Ichikawa sensei has mastered her ability to write characters and credible plots to a point that has got me amazed. Blue Sky Complex is a story with a high grade of realism; I can actually believe something like Narasaki and Terashima's relationship could happen in real life. This manga is a delicate piece of art, Ichikawa sensei's masterpiece.

It has a realistic pace, well-written characters, and situations. Even the ero scenes in this manga are incredibly well written; Ichikawa sensei approached sex in such a mature, tender and credible way that makes the reader experience that sweet feeling of being in the search of a pure love. I can feel the kind of love Narasaki and Terashima harbor for each other, and it's amazing how warm and honest it is. They have stolen my heart completely.

But, how is that Ichikawa sensei managed to achieve this? They key are her characters, and of course, their particular ways to see the world. After all, Ichikawa sensei is really good when it comes about POVs.

Narasaki and Terashima seem to be really different from each other, but they have more in common than they think. The former is a good student, and the latter is a bit troublesome, and both of them enjoy spending time in quiet peaceful places, so what better place than the library to make these two closer? After being asked by a teacher to work as library receptionists, they start sharing some time in the kind of atmosphere they like and getting to know each other.

Spoilers start here. I refer to the story a lot and make some comments, so proceed only if you have already read, at least, the first volume.

Spoiler (mouse over to view)
The story starts with Narasaki's POV, letting the reader know his impressions of Terashima. Narasaki doesn't understand him since he's so silent and acts indifferently, but thinks Terashima is an interesting guy based on what he reads, and there's something more just than his book preferences. Days pass by, and Terashima asks Narasaki some help with his studies, and also asks him for a reward if he gets better grades. Narasaki agrees, and tells him that he only has 300 yen and has to think in something that can be bought with that amount. Terashima accepts the deal.
Day after day after Narasaki finds himself thinking more and more in Terashima, and waiting for that brief time they share in the library before leaving school.

The way Narasaki is dragged to Terashima is so natural that the reader can infer easily that he's starting to like him in a romantic way, and is cute to see how Narasaki doesn't understand why he is thinking so much in this guy. Oh, that's it! The reader gets it: Narasaki has never been in love before.

Summer break arrives and their responsibilities as receptionists end, and they won't be doing the same job once they return to school. Narasaki keeps thinking in Terashima, in how nice was spending time with him, and in how great was finding someone to talk his interests and have a random talk.

Narasaki misses him, he enjoys being with him; he had a reason to like school, a reason to not to be bored anymore. Oh, but it's summer break! And he's bored in his home without anything fun to do!

Having nothing at home, he goes for a walk and buy something for his brothers. In his way, he meets Terashima, who was walking around to buy ice cream.

Narasaki feels happy. He didn't expect that meeting. The feels! Doesn't everybody feels like time stop and everything is more interesting when that one person you have been thinking about appears? Ichikawa sensei made a good move here because it's only obvious to the reader while Narasaki, being a dense character isn't even able to put into words all that. His very first time in the love department.

After sharing a short talk, Terashima asks Narasaki for the promised reward. Narasaki reminds him that he only has 300 yen, but Terashima tells him that the reward he wants won't cost anything. Narasaki is suddenly kissed by him. And in many other occasions after that, Terashima kisses him again.

He doesn't get why Terashima does it, but Narasaki starts to think he might be in love with him.

What is nice about Blue Sky Complex, is that Ichikawa sensei, as she has done in previous stories, once again plays with her character's POVs, and let us know the counterpart of Narasaki: Terashima, who is also a really well written character.

Under Terashima's POV, we learn that he realized that he was gay during middle school, and just to confirm it he accepts going out with a girl from another class. We also learn that he had his eyes put on Narasaki even before they met: Terashima was attracted to his gaze and looks; he was so interested in him that he started to get early to school just to see him.

So, Terashima does know he's in the love department, he's faster understanding himself than Narasaki, and that side of him makes the reader wants to know more about his thoughts and reason to act the way he does. Oh, man! This character is a total mystery during the first chapters, and damn! Ichikawa sensei has played a really good move with him! Why did he act so indifferent when he was with Narasaki at the beginning if he liked him before they met? I bet all readers were starving for this when reading it for the first time.

After being asked to be a library receptionist as a punishment because of his behavior, Terashima finds himself sitting next to Narasaki without having never imagined that he was going to have the opportunity to share some time with his crush. In this very part of the story the POVs collide, and the reader can know what was happening in Terashima's mind while Narasaki was starting to have an interest in him. Under that cool and mysterious facade, Narasaki saw every day, a really excited Terashima was hidden; his heartbeats were a total mess.

So that's the reason! Terashima was so nervous, and he, perhaps, expected Narasaki to start a conversation? It's really fun that they were asking themselves why the other was so silent at the same time. Terashima is afraid of having his feelings noticed by Narasaki because they're so strong and have grown since they met, but at the same time, he wants to be noticed by him. Terashima thinks Narasaki is a bit cold and strict, but he's also warm and has a complex way to see things, a divergent one compared to the people who usually surround him.

Finally, Terashima is who ends starting a conversation with Narasaki. And then the distance between becomes shorter.

He kisses him during the summer, and he does again and again in other opportunities until Narasaki realizes that he's in love with him, and a beautiful romance blooms.

I don't know if this exactly expresses all my thoughts on this masterpiece, but I tried. All I know is that I knew I discovered a good reading when I finished the second chapter.

What is this pure feeling

So, a yaoi/bl story that starts from friendship with good chemistry is always my fave. What's even better if it's slow, pure, soft, with eerie feeling and enough white space, allowing the reader some peek to each of the character's reflection for themselves.
Ichikawa Kei's manga is always like that, and that hits my soft spot greatly. The plot was slow, but, if you are looking for a love story that is realistic, gives you butterflies in your stomach, and sometimes stupid but sweet, this will fill your heart with pleasure. I just read the last chapter and God now I'm having a hangover over this. Terashima and Narasaki is such best friend and a great pair or lover.

Ichikawa Kei is a master character writer, and Blue Sky Complex does not disappoint. Narasaki and Terashima feel like real people and they actually build a relationship based on mutual respect and understanding. Their misunderstandings are realistic and solved with the power of communication which is pretty amazing. Highly recommended, it's a really enjoyable read!

The storytelling is so good....The way love blossoms between them, and how they are starting to change, or how their personalities affect the relationship. Their flaws don't magically disappear, which is so good.
I am trying my best to find stuff as good as this one here, and it's proving to be difficult. I have already read all the good ones I could get my hands on

Hey, a character who's actually gay!

It annoys me so much when straight characters in manga just suddenly turn gay for each other. It's unrealistic and belittles the experience of actual gay people. This manga does it right, and does it really well. Damn, but this is a cute story. The characters behave in a believable way, and their chemistry is off the charts. It's refreshing. There's so much sexual tension. Makes me grin from ear to ear. One of the best shounen-ai/yaoi I've read in recent memory.

Another gem in the pile! I love how the romance rolls with the 2 main guys, it's like eating a really delicious cake without the excessive extra whipped cream. Really, it beats the hell out of sickly sweet love stories or other mindless sex in the BL category. The art perfectly fits the story, and their inner monologues...PRICELESS! I love how Natsuki always fist pumps whenever he feels excited. SOO ADORABLE! It is series like this that I feel so giddy to be a fujoshi...(* w *)
