it ends with them "together" as far as them living together, (jiwook just becomes juyeons dog even further) but it doesn't end with them being a loving couple if that's what you mean.

How could he forget like that? Was it so insignificant for him to gang rape a highschooler like does he do that on the daily? Also when he finally realizes what he did what will he do? Apologize? Is it going to end with them two being together?
