Basically he went back to Yule
i actually think the ending was very fulfilling. you don't know if they are together after this. they just greeted each other, doesn't mean they are back together. it's an open ending, you can choose your own alternative. i mean, they have never talked, not for real, so i would expect them to get a 100% closure. and you can - as everyone else can - imagine how it went and choose your own final ending.
I know yule was fucked up in the head but I really wanted kyungsoo to get stuck with that bitch or kill himself. Anything is better then this ending it was so unfulfilling UGH!
