Don't hate on me, and please remember that reviews are just the opinions of the reviewers. This reminded me of A Love So Beautiful, which I didn't care for either. I was so looking forward to watching this, based on all the glowing reviews. Part of the problem might have been that I watched this right after Hidden Love and enjoying it so much. Maybe it just couldn't live up to my expectations. I was looking forward to this drama because it was supposedly low angst, and I was drawn to that. That being said -

WHAT I LIKED:
-It was, in fact, low angst
-the storyline of the second couple. I loved how he liked her alone and was always trying to help her in whatever way he could, even though his heart was breaking because she didn't like him.
-no stupid misunderstandings
-when the typical storyline started of a female trying to get the ML showed up, I LOVED how the FL shut that down. She knew her man, had faith in him, and went straight to the woman to resolve the issue.
-a wedding. Though, for me, it didn't work here, I always appreciate a wedding after watching a couple get together.
-ML and his dimples

THE THINGS THAT DISAPPOINTED ME
-FL. Supposedly cute and bubbly, she came across as a stalker (she was sure she liked him after seeing him once, and never tired of telling him that she liked him) and immature. The actress was cute as a button, but between her voice, her mannerisms, her clothes, and her bouncing around all the time, she just reminded me of a hyperactive puppy. Plus, her way of talking was very fast and staccato, like she was blurting out phrases, one after another.
-her calling him "Rang Rang" all the time. It was cute at the beginning, but by episode three I was ready to make a drinking game out of it - hear her say Rang Rang, take a drink!
-why did the ML like her? When did he start liking her? I get that he probably appreciated her energy compared to how repressed he seemed to be, but I didn't see or feel the attraction between them.
-I admit that I wanted low angst, but I also wanted something to move the story along. There really wasn't anything going on. I felt like I was watching a documentary of the life of a teen in China. I was bored.
-the parents fawning all over him was somewhat cute, but I can't believe they would have been fine with their daughter living with a man before they got married.

In conclusion, if you are still reading this, I'd say if you want something mindless to watch that doesn't have a lot of the typical tropes, you might enjoy this. It just didn't have enough going on for me.
