I don't think he's homophobic I remember in the first chapters we learn he has a bro-con so he's probably trying to protect his baby brother.
oooh that's tru but didn't taehee also say that his brother hated gays n anything related to the word gay in one of the chapters (i cant remember sorry)
I think maybe he put up that front to not disappoint his brother or parents, I've seen people in front of relatives get super defensive denying when anything is said about lgbtq+ and they are gay. I don't know I could be wrong.
ahhhh i see ok- welp we'll find out soon lmao
don't we find out later than the man is literally gay (or bi) as well tho wtf???? how we gon be gay AND homophobic tfff
