you aren't wrong? yiyoung didn't change that much he was apparently always like this but kang did, he started liking yiyoung after the one night stand (at the beginning) y'know? so yeah kang did but yiyoung didn't, also the story seems different because kang isn't meaner im pretty sure, they rushed kang and yiyoung together so quickly so that's probably why it seems so different

I feel like the tone of the story suddenly changed. I feel like im looking at two whole different characters right now. Maybe I should reread to see if im wrong or something
