It's a good story. 8.5/10. The story does a great job of making you hate a character, then like them, then hate them again. I respect that.
At first I thought the protagonist(Blue hair) was so cool and different. But then she ends up being one of the most annoying characters... I can understand the first time she tries to end the relationship... But then by the second or third time it gets a little tiring, it feels like that toxic relationship where they keep doing tests/jokes about breaking up.
And oh my god, I hated the red-haired girl. I think she must be the worst character from the story, and I feel so sorry for the girl who ended up with her. I mean, she forced an argument to happen so that girl would stop liking the boy, that's fine. But then she lets it happen and basically creates a whole situation where she is harassed and attacked by some men, is forced to flee, and in the end has no choice but to kill the guy... And all this for what? To force her to stop liking men. And you think she cares about the trauma? No, she basically uses the situation to exploit the girl even more and harass her even more, just like she's been doing from the beginning... I genuinely thought her sister would get involved and help, reconnect them... Unfortunately, she only ended up with the girl... It's actually quite crazy that the girl who's a walking LGBT agenda, who writes books of perfect utopias and happy endings, is also the most cold-blooded and heartless character in the story. Oh, and the princess from the other country, who is also the brother of one of the protagonists, is actually kind of irrelevant to the plot.
But anyway, it's a good story, the protagonist's(Bully) development is very complete, It's hard to see that around here. Honestly, I almost dropped the series at the beginning because I couldn't accept that bully would be the protagonist... Little did I know that I would be the best character.
