I mean, that doesn't take away that he was an ass to other people. A lover can love their gf/bf and be a total jerk to other people.
The fact that he didn't give a shit that an innocent boy was driven to suicide and acted like it was an inconvenience. I mean come on...
If a person doesn't give a shit about an innocent human life, he is a jerk. But hey, still love the uke.
I KNOW this story and have read it a million times, where in my reply did I say Siwon is Taemin? Siwon is GONE, he is dead. Taemin is inside Siwon's body so the seme did not help Siwon, he helped his old friend, Taemin. Taemin was the one who wanted to find the culprit. The seme actually stated that he did not give a shit about what happened to the REAL Siwon, which makes him a jerk.

If somebody wants to know why this manwha is BEAUTIFUL, I will tell 'em:
1. No rape, but only cuteness
2. The seme is so fucking dvcrxfbgtccbhbyxh (hot, handsome, gorgeous, etc are not enough)
3. The uke is an amazing kickass
4. Art style and plot are beautiful
5. You can read a sense of justice here (who didn't rejoice at the loss of the twin?)
6. Least but not last, they love each other, and they are honest with their own feelings!
