I feel kinda the same. I'm okay with ending and happy that everyone somehow got better, but a little unsatisfied. It's probably because my heart want to see more Yul... I just would like to see Yul being happy and enjoying his new live. I hope he will get a true love,nice friend/s and some good therapy (ᵕ﹏ᵕ)

yul was mentally ill yeah we all know that and its a given fact that if he stayed by sian's side he wont get any better and will stay obsessive
but idk man my heart breaks for him i just cant- bxisbxisbd i dont even care abt sian and yujin all i care abt is whether yul will get better and find a new girl that hes truly in love with and not the obsess type cause idk the words sian said to him was damnnn yep and i know it was needed so that yul can understand that its the end and he has to reflect on what he did but i cant like i srsly cant especially the letter he wrote oh gosh pls pls pls give some extras and timeskip or whatever that shows yul will get better and he will live a happy life with a woman he loves not obsess and healthily bdkbfjbsjd i srsly cant, i cried the whole two chapters when yul was faced by reality and when he wrote the letter while crying bcisbfjsbdj and the fact that his sis was sad too in the hospital when she saw yul like that omg i cannot my heart-
