I wouldn't say anything detailed here, all I can say is watch it for yourself to know and to see it for yourself.

The connection of EACH character is so good, like EVERY character has their sense. You'll get mixed emotions. See for u to know.

The cast? Their acting is phenomenal. Jihoon and Sangwoo NAILED IT. I love Lomon and Yeeun so much, but Jihoon and Sangwoo? Danggg, these two.

Tbh, I somehow get why some peeps said the ending was unsatisfying and a bit disappointing. But for me, personally, I love it. Just a right ending for this kind of drama.

Watch it to see, dont rely on reviews.
