Honey Bunny
Didn't like it. The guy was an asshole in the beginning and an asshole at the end and the girl selfishly chased after him like an idiot. And I'm certainly not taking his side, but if someone explicitly tells you to leave them alone and that you're a bother, selfishly trying to force your feelings onto them isn't love; it's an unhealthy obsession. I just couldn't find anything to like about this manga, unfortunately.
Doubt
Tags say it all: girl who was teased in middle school goes out of her way to be beautiful in high school and falls for the first asshole she meets. She then spends the rest of the manga chasing after him, shrugging off him cheating on her, disrespecting her, and generally treating her like crap. And the one moment she actually stands up for herself, tells him that he's not worth it, and you start to feel there's hope for her after all...nope. It's gone. The story immediately goes back to him doing whatever he wants and her chasing after him like a sick puppy. What a great message for girls: if he's rich and handsome, it doesn't matter how awful he is; one day you'll change him! Next time, I hope the author can write about a girl who not only improves her appearance, but her sense of pride and self-worth as well.
