Treize's Manga

Stopped reading ch 22
The plot is really interesting but it's no fun (?) idk. I kinda don't like that it's already chapter 20+ but there seems no improvement with their relationship and I hated how they treat youngwoong like is it not okay if he wants keep secrets from them? They said it themselves that they barely knew each other but there they are crossing the line.
Tbh, the only thing that keeps me reading it is bcs I wanna know what kind of animal is youngwoong (PLS SPOIL ME!)
Anyway, I'm not sure if this really worth to read. Pls let me know ur thoughts.
