That was make sense like, since that psychopath Chinese asshole used to use the envy stone because of jealousy, i guess
woahhhhhh
Now this is not confusing anymore. Thank you, my friend. ヾ(❀╹◡╹)ﾉ~
But in doing this from what is implied by the note he doesn't think he will be the soulmate because Jinha is literally sacrificing himself to be hated by Siwon so he can find his soulmate without his interference, if it turns out it isnt him after all, and Siwon wont have to worry about the China boy any longer cuz he'll be stick with him instead.
Jinha is making it so Siwon can escape without China boy using the envy stone cuz if he gives him attention he'll be obsessed with him instead. I do hope they meet tho and it isn't revealed Siwons mate is another.

For people who don't understand (it took me a minute), I think he's saying that the envy stone only works when the person who has it is jealous. Since Kang Jinha is showing Seonyun all of this attention and slept with him (maybe but hopefully not), he isn't jealous enough to power the stone anymore. That means since Siwon has the fate stone, he and Kang Jinha can meet in their dreams without him interfering, finally bone, and then dip before he even knows what happened.
