The next chapter is season 1 finale, and I think now that finally Jaeyi realized how he feels, he gonna quit from the friends with benefit relationship, because just like he said, if anyone start to feel something, they quit, and that glance to the judo uniform (quitting), I think he gonna leave Ideum, this gonna mean the regretful top hashtag.

Jaeyi will distance himself from Ideum pushing Ideum closer to Jiseong and the Jaeyi losing it.
I hope this never happens though, all Jaeyi has to do is realize he loves Ideum already!!!
