True people saying wataru is at fault and all not everyone are so sure of their own self in teenage, it's changing phase of life meeting new people with different dynamic make changes in your character especially when one tend to make one in your life in bold behaviour like this uke did.
most people are not sure of themselves for who they are when they are teenagers. I know people think that queer people notice their sexuality from birth, but some of us take really really long time to notice it, I noticed I'm gay till I was 23.
True , I m straight but I have male gay best friend he didn't realise he was gay till he entered 20s now he has bf people are just not so sure sometimes also it's hard to figure out till they get into a environment where they can open up themselves life is all about exploring yourself and how much limitations you can made for yourself only by figuring out.
damn, he went from I'm not gay to dating my childhood guy friend to getting dumped by my boyfriend to finding another boyfriend in Light speed. tbh that's what it's like to be a teenager
