IT IS AMAZING.
What's wrong with a homosexual scene? Good stories cannot have homosexual characters or a homosexual scene or people doing drugs? What?
You try promising to wait ten years to have sex with someone you've known for a couple days. What, the main character was not supposed to sleep around or something or what?
Not only that, he's not a fucking wimp like every single other romance/sports manga character. Sure, ego huge as crap, but he actually backs it up.
The female character is so fucking refreshing. She's not annoying, she's not stupid, dumb, or etc. She has strength but can cry, she has insecurities that she voices, she knows what to do, she's scared but faces her fears.
Other characters are nice and memoriable. I wish there was an extra bit to show a bit more of a conclusion, but what they had so far was amazing.
Overall, definitively good characterization.
Art is so cool. The last page was so damn cute. I know no problem with this crap.
I enjoyed reading it, I seriously did. I don't see the problem. A mature manga, yes. Amazing. Shit, I loved it.
