I don't know if you finished it, but I hope you have - Jaeha actually ends up confronting his feelings and all the miscommunications and we get a deep look into his (honestly tragic in a way that just makes you feel sad and some pity) backstory - and a more raw look into Eunho's thoughts and feelings. It's a wild ride, but finishing it definitely made me more relieve than if I left it at chapter 25 like I wanted to.
I did finish it, and his development was nicely done but yhe first few chapters were ROUGH
IK The only thing that powered me through was the barely hanging hope of something gonna come out okay and certainly the lack of sleep that lead to loss of brain cells which kept me insane enough to finish this, thankfully for once.
Ok im on chapter 15 so far, but i cannot handle how i feel about the dude with black hair. Its like hes just playing with everyones feelings i feel so bad
