This was.. a ride. I stopped when I started reading 5 chaps of the side story because I couldn't imagine how it will go, but here I am. Personally, I hope Do-Hyeok learns his lesson and NEVER see Siwoo again. They both deserve better and a sad endgame would be nice for a change.
I've finished reading this from another site and I'll tell y'all, I didn't stop reading because of the suspense every end of the chapter. But hey finishing at 2am is worth it (╥﹏╥)
dropped this for a long time and came back because of spoilers. I feel bad for Cain, he's such a sweetheart :'(
