hard story to rate

Rating: 8.9  / 10.0
I've read this story 1.5 times, so I do enjoy it. The art, the cool female lead, interesting male leads and side characters, and unconventional story plot are all major plus points for the series. Also the villain was my absolute favourite type ie intelligent, manipulative, gaslighting, psycho charismismatic trash!!!
There are however some cons that detract this from being a higher rating for me. During my first time starting this, the shift in theme and how ship that I had secretly enjoyed turning into a probable end game couple was shocking. Also I loved all the side couples/storylines but the switching between fluff to angst to plot development felt jarring at times. The story also felt too long.

However I did give this a pretty high score because I did really like this. It definitely felt fresh, and the ending scene made me cry yall. Hope the author has another series in the works because I will definitely check it out.

I loved this read, it kept developing in an unexpected way and the I was actually satisfied with the ending. I’m so happy I read this and stuck with it, it’s like the chicken soup of manhwa.

There were parts that dragged a bit, but never for longer than 2-3 chapters. Lots of comedy 🤓 I found myself changing my opinions about each character as the series went on, pretty much everyone got fleshed-out character development.

Good, but the story is longer than it should've been.

- Strong FL
- Complex characters, complete with tragic backstories
- Good comedy
- Slow (like, are-these-two-gonna-bang-later-or-am-I-just-delusional type of slow) build romance, which I suppose is understandable, considering their circumstances.

The author tried to drag out the story and it clearly showed. I remember I'd dropped this manhwa once because the plot was too boring and needlessly long. The only reason I continued reading it again a few days later was because I'd already gotten attached to the characters. I had to drag myself over to the finish line, so to speak.

This is a good manhwa to read if you have a lot of spare time and you want to read about some high school students (straight or not) figuring out what love is. They mess up along the way, but they'll get there eventually.

This is one of the freshest webtoons I've read. The characters actually have substance to them.

Only thing I'd say is beware, you'll be binging this thing before you know it lol.

Highly recommended.

I enjoyed this series a lot, and although there were a lot of confusing parts, it still got my interest. I'm happy actually happy with the ending.
Spoiler (mouse over to view)
Got caught. He really did love Hanmi, and wanted her to be with him despite the things he did. He just couldn't accept that there was someone more important to her than him. He was fucked up, but he did love her in his own way.
Spoiler (mouse over to view)
As much as she tried to downplay her feelings to Gun when she was explaining what Jun Hyuk was to her, it was clear she couldn't take the first step, or be the one to first admit it. She could never take the first step because she was confused about the depth of her feelings. Was it pity? Was it romantic? Was she just feeling sorry for a relative? She knew how Jun Hyuk felt, but since he was distancing himself from her, she decided to do the same. For her, going away was the way she could sort herself out. But from what she said to him at the airport, she already knew how she really felt for him, and was just waiting for him to define their relationship./
Jun Hyuk
Spoiler (mouse over to view)
Although he had been protecting her all the time, he had never taken their relationship in a romantic direction out of fear of being abandoned/orphaned again. Despite having kissed her. Even though Hanmi asked him twice to tell her how he felt, he never did. Hanmi even thinks "Why won't you believe you won't lose me." while sleeping at his place. Maybe she wants him to have faith in them? And after 2 years of not seeing her, and sorting out his feelings, Jun Hyuk finally gets the push he needs after he's drafted for military service.

Good but can be irritating

It's a good webtoon, but there were a lot of slightly irritating aspects. I liked the main female lead but she seriously has a communication problem. A lot of times there was no reason at all to keep something secret but she did anyway. A lot of characters had this problem too. I liked that she was a smart MC but I feel the webtoon pushed the "she's really special" thing a bit too much. Every time a character tried to resolve a conflict they usually failed until she got involved. Which was kind of annoying.

Also about 100ish chapters in, this becomes a reverse harem in a sense (she ends up with 1 guy tho, don't worry. And it's the ship most of us were rooting for anyway). There's about 3 guys obsessing over her at that point. It was just tiring. Loved her for 10 years? Created a complicated, illegal scheme to get her? All that and more. It was too much. Like she's cool, but she ain't that cool dang.

There's also like 200ish chapters which, considering the plot, really wasn't needed. Could've been completed in half that.

One nice thing about this webtoon though, is how casually both GL and BL elements are incorporated. Webtoons/manga usually have every single character straight or gay. So it was cool that among the main cast,some were straight, some were not. Heck the healthiest relationship in this (imo) is the GL one.

Anyway even though I liked it for the most part, I prefer the 1st arc by far. It just gets so much more needlessly dramatic/complicated as it goes on.

I feel like I mostly criticized it lol but overall it really wasn't a bad read. Could've been better, but it's still worth a look.

Hooks you but dreadfully slow pacing

If you came for forbidden romance uhh you will get it. Eventually. Its such a good read with the comedy, characters and drama but geez. They really are milking it as long as they can. The moments of romance between the 2 main related characters are few and far between. Its super subtle otherwise which makes you feel like a lunatic hoping for more concrete evidence. After ch. 120 the author answered some questions in a author page and she hinted that the next volume would include more definite plot surrounding the male's feeling for his cousin. I would recommend this manga if you want to get hooked and feel frustrated too.

Toxic and Addictive  
by lilmsotaku23

Rating: 9.0  / 10.0
I just finished binge-reading this one (Chapter 0 - 153). When I started reading it I thought it would be a light manhwa about crushes and misunderstandings and oh boy I was wrong. I actually like and adore the story because it's realistic - the bullying, family complications, LGBT concept and etc.

but seriously though the relationships are really complicated! - I don't know what ship to sail, I both like Junhyuk and Gun for Hanmi, and even if Seonghwa's quite the psycho he's really hot (for me).

Spoiler (mouse over to view)
** It's quite clear that Junhyuk likes Hanmi.
** I feel like Hanmi likes Junhyuk too - though she might not be aware of it, because if she doesn't have any romantic feelings for him Seonghwa, Gun and even Junhyuk's gf wouldn't feel bothered at all.
** Gun and Hanmi's relationship is quite toxic - I don't know if they really like each other romantically or they just simple like each other, infatuation perhaps? they're not open with each other, lack of trust and communication - but they're really cute together. maybe Hanmi likes Gun because he's different from the people she knows, you know like the boy next door type who loves his family wholeheartedly.
** Gun and Jua's relationship is full of misunderstandings - I'm glad that they were able to talk more openly about their feelings on the recent chapters - Jua's probably hurting since he feels that Gun is just staying with him out of pity since they had a misunderstanding before his accident - Gun is too dependent on Jua, Jua became his comfort, he felt that he's the only one who can take care of Jua (I'm not sure with this one but he was feeling uneasy when Jua made friends from school and he even thought of becoming a Doctor in the future for Jua)
** Seonghwa and Hanmi - their relationship is messed up, hoping for more flashback since it's still unclear on what really happened with all of them.
** Yueun and Go Jun - finally became a canon!
** Junhyuk and his gf - oh boy I hope he won't fall deeply inlove with her since I'm still rooting for Junhyuk and Hanmi - though the gf is quite smart and cool too.

and... who is Junhyuk's real father?

How about Hanmi's father? I feel puzzled when Junhyuk's (supposed) Dad jokingly told Hanmi's Mom that he might be her father - Does that mean they had a past together?

I'am so full of questions right now and having all these mixed emotions.

Simply wonderful.
Complex characters? Check.
Complex relationships? Check.
Realistic development of relationships? Check.
Great pacing? Check.
No sexism, no homophobia, friendships are as important as romance.
And what makes it so appealing is the storytellig and the conversations! I have read so many stuff where there is no homophobia or sexism or whatever, but a lot of them felt shallow. This one, however, was so thick and beautifully written, that I needed to ask myself questions, and I became conflicted about several thingd that happened in this webtoon, just the way the charafters became.
It feels like they are all too real, and they are all so different, with their own faults and qualities.
Aaaah I can't simply say how satisfied I am with this webtoon!!! It is not just rare, it os just perfect! I can't even convey my feelings about this webtoon!!,

As a webtoon, this story feels refreshing, interesting, fun.
All the characters are likeable, different and interesting. Our main characters are incredible funny and well made.
Webtoons are getting a lot of attention, as is really interesting to those manga fans who want something refreshing in the genres. This gives exactly that, specially when is about the characters.

Hanmi, our strong and independent heroine, and her cousin, changed school because of something that happend in their last one, which we only get hints of but they dont tell us - yet. She starts liking one of her classmates, and makes the wrong decision to say that they both, she and her cousin, are dating.

EDIT: So far I'm on chapter 120 and I have to say that I'm a bit dissapointed, this could be even better. Of course I'll finish it because it's interesting and funny, and I want to know where is it going.
