This drama is all about the ups and downs in a relationship, as the name suggests. The drama wasn't bad. It's a cute drama (not always). It dipped real hard in the middle for couple of episodes but it got better in the end. The casts were beautiful. The story was ok even though the romance was messy. They used some classic and famous songs instead of using one original ost so the music was ok.
Overall the drama is ok and if you can get past the dip in the middle then it's a cute watch.

It's just the usual rom com with lots of love-triangle (lots of them), bromance and jealousy. The problems in the relationship between the MCs were somewhat realistic so its kind of relatable. What a couple goes through when they are dating when they have different values and etc. It's not a bad drama by any means and if you enjoy some realistic feels then you would probably enjoy it.
