I haven't read this new story, but when I originally stumbled upon the name Jun Lin Yuan in DKC, it made me curious so I did a quick search for chapter title names to see if he shows up. I read like 2-3 chapters hundreds of chapters into the story. Apparently, Feng Wu and Jun Lin Yuan are not a couple at that point in the story. All I know is that JLY likes FW, but he shows it by bullying her. She hates him, not surprisingly. FW tells some guy she acknowledges as brother about this and asks why he doesn't defend her or go kick his ass. Her brother responds about how some guys display their affection by bullying the girl they like. She finds his absurd and immediately confronts JLY and asks if he likes her. Inwardly, he thinks to himself he does, but seeing the way she's looking at him, he decides there's no way he's going to say yes.
That's all I got. I don't know how he was bullying her.
Just like Nangong Liuyun, this JLY guys is also probably an asshole. Possibly even worse than NL. Makes me want to read it lol
