SPOILER ALERT!!
.
.
There are not that many chapter left.
White hair guy gets caught. He really is not that relevant to the story and we won't be seeing more from him. Chamin went out publicly and pretended to cheat because he wanted to caught white hair guy.
After mogyum and chamin get their happy ending (we get like 3 chapters of steamy sex), Chamin gives him a ring and all, then we go to the other couple. Turns out that Doyoon was actually in love with Seungho this whole time. And after a third party gets briefly introduced (mfs because I was shipping new guy with Seungho) they show us that they're both the same. Doyoon and Seungho suit each other in their twisted way and they end up together leaving new guy being totally a collateral damage. That's what I disliked about this story. That they gave Doyoon and Seungho a happy ending too. Seungho didn't deserve it, not even after showing us his before and after everything he did. He had, at the end, two guys willing to do everything for him but he didn't deserve it.
I can't comment anything really cuz i already finished this story. But oh well, some people are gonna get real mad and some other softies will be glad. Anyway. Enjoy!
