Was the professor Jaeha's First?

yes.

thanks for the reply! I was a bit sad that was his first >_< but I guess someone has to be. Do you by any chance know why he went with the prof? I know he meets Hanjun later, but was he with the prof because I guess he wanted attention or something?

He fell in love. That’s why he didn’t want to date after the professor broke his heart bc the shock and sense of betrayal was too much.

thank you :D that makes so much more sense!

hey! thanks for your replies, I just have one more question. What do you think the prof meant when he showed him the picture of Jaeha and him having sex on his phone and says "are you ok with seeing your friends like this? is that what you're saying". Is he just threatening him? cuz I know thats a different picture from the one his classmate sent around.

nvm, I think I understood, I forgot that Jaeha mentioned something about not wanting his friends to know previously, so by threatening him with the pic, the prof is telling him to drop it.

Yes! He was threatening him :(
