I think the big bro is smarter and kinder than that. He might be like do you know what it means to be gay? or like since when was this going on? then the author might have a side story about the big bro, and I'd be happy. I don't think there's going to be drama with the big bro.
You're right, I also think its gonna be something like that <3
Hopefully the big bro doesn't go into "I'M THE ONLY GAY IN THIS FAMILY, YOU ARE NOT ALLOWED" or "OH NO, DID I INFECT MY GAYNESS TO YOU DEAR BROTHER?!?!"
It makes me more nervous to see his reaction as him being gay than if he was straight
