if im being honest, its not that i think yuu is a piece of shit, he hasn't done anything that was bad as aya, she's actual piece of shit person for the sugar dating prank, if u can even call it that. My problem with yuu is that when you reread the manga, yuu is so dishonest with hakari, esp with the kiss moment. Yuu is not a trustworthy person. he has had several moments where he couldve been truthful of his feelings and insecurities, but he chooses not to say anything or lie. Esp with that kiss moment, yuu was never gonna tell hikari about it if she didn't see them. And yea they're teenagers, and all teenagers are stupid. But So many of his actions have been dishonest, i have no faith in him. Yea I'd want him to be a better person and grow up, but everything he's done, hikari derserves so much more, she derserves someone who is honest and treats her with respect.
