It's not going to happen, as Jinha will forgive Siwon due to his dependency issues with him, and they will end up together in typical yaoilogic, but a more twisted, interesting conclusion, seeing as Jinha is going to end up miserable regardless could be:
Siwon confronts Jinha, he tries to plead that it was the magic stones and Chinese guy's manipulation which made him behave so badly towards Jinha. Chinese guy is sitting in the corner pretty overseeing this argument, from his perspective, he has achieved his goal, his Jinha has came running to him. Siwon was just the bait. Jinha rejects Siwon, says he can't forgive him, that even before the stones he treated him like an enemy. He walks over to grinning Chinese guy and kisses him, not just the pecks that he used to give Siwon, buy a proper kiss. Siwon runs away in tears, job done in severing that relationship. Chinese guy is shocked, he wants Jinha in a possesive way, so accepts this new version of him. To continue the BDSM theme, Jinha makes the Chinese guy his "sub" partner. Chinese guy never cared for Siwon, so he is content with the object of his affection giving him his full attention regardless. Jinha though seems to be getting a lot of pleasure in inflicting pain, but Chinese guy just presumes this is their role play. Months, maybe years pass. Every so often Jinha will mention Chinese guys past wrong doings as a means to keep him on edge. Chinese guy is constantly stressed that his obsession is going to leave him all alone, so tries to repent and be nice. Jinha provides him with a sense of security, reassuring him, only for him to wait until Chinese guy is at breaking point in terms of just how emotionally dependent and stressed he is . Jinha abandons him. He doesn't even tell him to his face, but instead just leaves a note saying that if he ever makes contact, then he will go to the police, as he has spent their relationship recording all the times Chinese guy apologised and confessed his crimes.
That's rather evil I know.

(⌒▽⌒) interesting idea . I've been laughing at all the crasies the author has been throwing to the story . At this point it doesnt surprise me .
But Im hoping he'll end up not choosing anybody and go on his way . then maybe later develop something with jinha . but id prefer for him to be independent .
Please tell me im not the only one who's laughing at this point with all the crazes . LMAOOOOO , i cant handle . Adsnalnflk
