I kind of have a feeling that this new guy will try to do something to DG..it's clear that he likes him

I mean. Not really.. I don't really see Jaejin liking DG. It's more like Bromance. Not all friendships between 2 men means they're gay..
A man can be friends with another man without it being gay or anything like that...
Jiwon is just jealous and wants DG back so he is very envious about Jaejin.
*BUT* If Jaejin actually likes DG.. then we have a problem.

Am I the only one expecting a happy ending for Sangwoo and Bum..

you are just as crazy as them

I never said that in any part of my comment. I just said that a happy ending could be interpreted in many ways like them landing in a mental hospital lol which I would prefer since that would mean they were caught and also getting mental help. I never stated which ending I want and the moral of the story will still be there no matter the ending and it is definitely not to just let people rot away in prison. You have many books where things happen which are the exact opposites of what the moral story is. For example crime and punishment where raskoljnikov almost till the end doesn't recognise his crime for wrong or combray where rastignac never changes and just gets worst with time and socially climbs like a master, aka displaying behavior contradicting the morals of the story. Basically the authors explain what is good behavior by showing you what is bad behavior.
But Jiwon's face when he saw DG
