I think it's called gay panic. Realizing that you just do that kind of stuff with a guy is pretty gay so he was scared and what do most people do when they're scared. They run away from it.
He left 'cause he was embarrassed he took advantage of Yusuke and he misunderstood what Yusuke had meant when he asked "do you think of me as a girl?"
Daiya thought he had forced himself on Yusuke and then made Yusuke think he was supposed to be a replacement for a woman since there were none around their age in that town.
He came back after realizing what Yusuke had really meant-- which was actually "I'm not so weak that I can't defend myself." Ultimately, if Daiya had really forced Yusuke then Yusuke could have easily fought back and defended himself. He didn't 'cause he wanted to have sex with Daiya as well therefore Daiya didn't rape/force him like Daiya had thought he had done.
Nawww when Daiya had the flashbacks to all the times Yusuke was carrying heavy shit and being all macho is when he realized that Yusuke meant that he wasn't defenseless and could've fought back easily if he didn't want to have sex lol Yusuke wasn't meaning "do you see me as a replacement for a woman" but that he wasn't defenseless.
When tf did I say that? I, myself, am in a wlw relationship and quite frankly know a lot more about how homosexual relationships actually work out in the real world than most people online do lol You probably didn't mean it this way but next time be careful 'cause someone could take offense to unsolicited advice.
Also, denying that homosexual people can't be "feminine" or "masculine" is denying those who are their right to be who they want to be. I've got a few buddies that would happily argue with you who are either in favor of being one or the other lol It's not "heteronormative" it's letting people be whatever tf they want to be, sweetie.
Can someone explain chapter 5? I dont get it why did he leave or any of it by the time he left countryside
