I think partially he’s using sunhwa to hang onto nanjo. In his mind, if sunhwa is out of the equation then nanjo wouldn’t be in MC’s life anymore. Since he doesn’t know if he likes him back, etc
That and I also think that he's sunwha was not the type who would be forgiving when something/one was taken from him even for a friend.
That makes sense, but honestly we haven’t seen sunhwa backstory or even what he thinks, he’s just there to do sex and doesn’t like relationships. Like maybe he wouldn’t mind because he would rather not have a serious relationship.. plus they been friends for 10 years.. but we will see how it all goes down last chapter..
Ok so, we all know that the main character and sunhwa? They were friends for 10 years. Like I’m just wondering if the mc just told his friend that he fell in love with black haired guy then the friend might’ve been understanding? And let him have him. Because we can see that sunhwa don’t gaf and just wants to have sex.
