Agreed! I think the development in BJ Alex also wasn't gradual, it was due to a sudden situation that catalyzed the change. Probably it's the same here, we won't see any progressive/slow development until it's forced by something like Dan dropping him
If Dan really does leave him I think it’s going to be because of the grandma, like she might pass away or something.
Yeah, the grandma seems like an important part to make things move forward
so in Jinx's earlier works like BJ alex, it's always the same. the character doesnt really get character development until the main character leaves. so until he leaves in my op JaeKung isnt going to get any character development until it's too late （￣へ￣）
