I don't think Jaehyuk is going to take homophobic ridicule the same way Garam does. If he does get attacked by homophobes, he will likely get over it quickly because he is written with a narcissistic personality trait; however, having experienced it firsthand will help him to understand how cruel people are towards gay people, through a first person pov. Seeing Jaehyuk being bullied for being gay would feel to Garam like reliving the past, so that's why I think Garam would have an extreme reaction to seeing it, even if Jaehyuk himself doesn't let himself be affected by it.

feel garam nightmare has come he doesn't wanna get bully or be a topic for gossip but now whatttt yall hating on person who got bully betrayed like no one on his side with person who somehow turn on gay mode and then turn off gay mode when break up
