I thought this was a particularly nice rom-com to watch. There wasn't much that I hated/ would improve about it. I loved the pretty realistic setbacks the two main characters experience to bring them to the worst slump of their life. I love the emphasis the show made on mental health, friendships and family values. The character's struggles and life experiences seemed very relatable and I loved the story all the more for that.
I could see why this drama might seem a little plain for some as the romance was very calm and the 'enemies to lovers' part that they signed up for was immediatley resolved. There were no dramatic scenes or villans and no romantic scenes that made me want to scream and bury my head in a pillow.
The scenes with the family, the second couple and the comedy in the drama was also very well done! Some of the comedy scenes really got me smiling from ear to ear and of course park hyung sik and park shin hye acted so well in their roles!

Overall a really nice comfort watch, just what you need to get over your drama watching slump :P
