“For no reason”? Lol Hina isn’t a kid. Sure she’s a teenager, but she’s not clueless or stupid she knows Taiki already has a girlfriend. Just the sole fact that she’d kiss someone who’s taken is already messed up. She’s not some saint. Honestly it just shows Hina doesn’t really have anything going for her besides liking Taiki. What development has she had so far? None, other than her silly crush. Ayame, Kyo, Chinatsu, even Taiki all have way more depth than her.
Kyo didn’t even kiss Ayame when she had a boyfriend because he knew it was messed up even just on the cheek but sure bud Hina is an angel who can't do wrong eh
Overdramatic commenters acting like a kiss on the cheek is the worst crime someone can do, please live in reality and smell fresh air, the kiss on the cheek itself wasn’t a big deal, it’s the meaning behind it that made Taiki and Hina pause. Also reversing the roles isn’t fair at all considering the context of this story, just say you hate Hina, a literal teenager for no reason and fume by yourself.
