**opinion after reading raws**
Honestly poor Jiha got cheated on, so no wonder why he is bitter since he loved her and got her a RING, then discovered her and Chulsoo. Ye-eun just uses them all I'm honestly not surprised how Chulsoo is due to the fact how much Ye-eun has used him and he feels special in a way and I'm not condoning any of their behavior this is just how I feel and honestly none of them have behaved in a proper manner let's be real lol
mainly here cause this art is beautiful
