I think it was abt the studying abroad (?) but as Juheon told his Grandpa that he didn't want to and walked out, his mother/aunt followed him and somewhat pulled the "I'll do something to him(Dohu) if you don't listen to our request" something like that so He had to go overseas to protect Dohu. (?) I'm rlly bad at explaining and my memory’s shit so I might've gotten something wrong
Ahhh I see, thank you!!
Juheon discovered that Dohu was using him as reference for his novel and thought that Dohu was only together with him just for that reason. Which was partially true because Dohu got together with him just to observe him and his reactions as reference but eventually he fell for him too.
Can someone remind me why they broke up? I remember that Dohu used Juheon for his novel, but it's implied that the seme also left to protect Dohu and I just don't understand why (and am to lazy to reread )
