Haha you know what’s funny my friend on here has actually called me out for always giving Mnh abusive/shtty ex-bf’s all the time in my fic ideas 😂

I But oooo I love the idea of jealous competitive Jsng!! There is a fic with a plot that is similar to this if you wanted to take a look, though I admittedly did not finish reading it at the time it was being posted but it is completed now: https://archiveofourown.org/works/59052460/chapters/150552733

A fun twist on it though would be Jsng being inexperienced like you said! Maybe he has a crush on Mnh and he’s been watching him go through relationships from the sidelines and even though he’s never been in a relationship himself, he knows everything there is to know about his best friend and he’s determined not to make any of the same mistakes Mnh’s exes did 😤
