A collection of stories:

1-3. The Heart of Miscalculation
"Why don't you date me?" And that's how Miki started going out with Udou, from next door's classroom, who was fighting with his ex-girlfriend. It was because of a whim, just a "game". But being with Udou, he started getting comfortable? During the sex, Udou took control of him with tricks, making him tremble in pleasure. Tender caresses, sweet passion? What happened to my body? Damn, I'm not like this. A traditional boyfriend, and a boy who likes to flirt. A story of pure and immoral love between high school students.

4. Last Summer Blues

5. A Vulnerable Afternoon

I really like how Miki never ran away crying or internalizing when he had a problem with Udou. Instead of getting sad or scared he just got pissed, which is what I've wanted to see an uke do for a long time. I also liked how both the characters interacted and their relationship dynamic.

I was pleasantly surprised in reading this yaoi, my first by this mangaka. The art is really quite beautiful. The clean lines and stark,mostly black and white palette are refreshing. I enjoyed the story, too - it's cute and sweet and hot and, again, a bit different from the norm. As another reviewer mentioned, it's nice to see the uke with a more equal role, especially when it comes to initiating and unabashedly enjoying the smex.

Dont hurt me Chise

Although I love Ogawa Chise's work, this manga did not touch me in any particular way. Maybe I found it too unoriginal. Two ordinary school boys falling in love with each other, bit of jealousness, bit of angsty and ... that is it. Finito. It still great manga though but nothing to compare with her another work.

Was thinking of rating 7, there were some light (dirty biggrin ) moments, but after the ending chapter I reduced it to 6. Really, what the h*** was that? Totally unecessary scene with Udou's brother full of cliches? Yuck! Thanks no.

Definitely not for non romantic lovers who are not seeking for anything but sweet nothings. And, which I found the worst, there is no deep meaning neither advice of any kind.

Cute and lewd xD

I really enjoyed this. The art style is pretty and I like the personalities of the two main characters. They mix the traditional cliched characters enough that these guys are fun and interesting. You've got to wonder who is really the lewd one between them... I've got to admit, the characters turned out to be quite different than what they seemed to be at first on the surface. Only thing I would have liked better is if there was more of this story! Recommended (unless you hate characters who sleep around - if so, why are you bothering to read the reviews to this?). It felt refreshing.

Ogawa Chise really outdid herself in this manga. In contrast to the usual yaoi manga where two guys meet each other due to certain circumstances and suddenly fall in love with the usual dose of sex, sex and sex, this yaoi manga is surprisingly different.
Each character has a unique side to themselves which makes this story so romantic, and the desire they have for each other is so overwhelming. The author has made sure that everything is carefully laid out in the three chapters with two extras, and one can't help but fall in love with the characters even though they can have their own flaws. They're just to loveable which made the manga shine even more.
A must read for yaoi fans.

This makes me so upset because I'm not sure if I like it or hate it. I mean.. the characters are lovable and the story is cute. The way they interract is interesting and their love that develops is precious! But then there are the stupid yaoi-clichés that just irritate the fuck out of me. I like it but the clichés distract me but in the end I still enjoy it.

This is the first completed manga I read from the sensei that I found every story satisfying from the main story to the two short shounen-ai stories. I enjoyed all of them so I'm giving this whole volume a 9/10.

Edit: Loved the cover art, hair styles, colors and that shoes design of this manga.

After just 2 chapters, I already really like this story. Normally womanizers annoy me, but Miki is such an adorable brat, that I can't help but love him. And Udou is a brilliant seme. He's intense and possessive (you'll see what I mean at the end of ch 2!), and he strikes me as a closet sadist too. Also, both characters show love and desire for the other, which even includes Miki being the one who comes on to Udou a lot, which definitely makes a nice change to a lot of standard BL where the uke will say "no" when they really mean "yes". And of course, as with all of Ogawa-sensei's newer works, the art is beautiful.

While this may not be everyone's cup of tea, I personally love this. 10/10 so far.
