BTW; This doesn't contain any spoilers but it can spoil the dynamics between the characters and such.

I barely have any negative comments for this tbh, it's just so good. Binged watched the whole thing in less than 5 days (I was on break I swear I have a life). Okay, I said I don't have any negative thing to say but tbh I can be a bit stereotypical sometimes, but other than that it was an amazing show. Got really emotional sometimes, her dynamic with Junho was really sweet, really loved how he was so patient and understanding with her despite the lack of attention she gave him... AND PLEASE HER FRIENDSHIP WITH GEURAMI, please I strive to have something like they do. Kinda did have a bit of a crush on Minwoo when he wasn't being a b*tch but anyways... He and Suyeon were cute (once again when they weren't being major b*tches T-T)
All the characters had great chemistry with each other; romantic, platonic...etc and the acting was chef's kiss as well. Definitely one of my all time favourite K-dramas, It's sooo good would definitely recommend it.

PS: I don't pay attention to OSTs and music in dramas so don't completely trust my rating on that.
