There were a few things that annoyed me about some of the characters.
Beware of small spoilers. I actually really liked the first episode and how they started with a misunderstanding and how everything got resolved little by little. I would say two of the things that most annoyed me was how the female lead left like two times throughout the show and also the ending was good but not satisfactory. Gao ya character was really something, we could of avoided so many things if she just listened to others and didn't do things how she wanted
