I don't know y i'm happy that in the end they r together .

:'> perhaps he was thinking he at least had to make it up to Kyung- soo or he owned Kyung-soo an apology :'> sure Yule still had feelings for him but in my opinion, lovers and couples can't work it out when things get this messy :'> all there's left between Kyung-soo and Yule are horrible and sad memories :'> Yule were definitely guilty about all the horrible things he had done and he can change to be a better person in the future but that doesn't mean we know for sure that they'll be able to patch things up and Kyung-soo will forgive him

Likely, Yule continues to follow/stalk Kyung Soo because he cannot let Kyung Soo out of fear of abandonment and guilt. The way I interpreted it, Kyung Soo was able to break out of the cycle of being dependent on Yule by leaving him (Yule was able to utilize this dependency and fear of him to blackmail Kyung Soo into staying with him). Yule, in contrast, enters a state of dependency with Kyung Soo, so he cannot let him go and needs him in his life. Of course, there is change with Yule and he doesn’t act impulsively anymore because he feels guilty and is aware of his actions (his future actions could push Kyung Soo completely out of his life), but well, simply put— he cannot live without Kyung Soo.
It is a shame that after destroying his relationship with Kyung Soo (due to gang rape, rape, blackmail), then he realized that Kyung Soo had actual feelings for him. Now that he developed feelings for Kyung Soo, he is in a continuous state of fear of having those feelings being unreciprocated and Kyung Soo disappearing from his life.
Sad, it is like Yule knew what he had (Kyung Soo’s feelings) and went on to destroy their relationship because he never thought he’d lose it.

I agree with you— I don’t think Yule and Kyung Soo should end up together. Of course, they can be in each other’s lives, but a relationship isn’t likely. Their relationship, the way I see it, is like broken glass. You can repair those broken and fragmented parts together with epoxy glue, but you still have glass that was never restored to its original state. ╮( ̄▽ ̄)╭
