This one is a very light and easy youth drama which you won't regret watching.
Firstly, I found this drama after watching Love Equations. Struck by second lead syndrome, I searched for Li Ge Yang's drama and found this. This is his first Main Role and I am interested to watch it right away.
The story is identical as the youth dramas you all usually see. Haters in senior high, then became lovers in Univ. Misunderstanding and family problems occurs then some jealous and missing moments. But the cast really nailed it! They are just extremely cute and fun when they are together. First time seeing the FL, she did it well. Waiting for more of her projects. Her acting is just soooo cuteeee! The ML also acts good, with the personality transition and the secret love between the 2. Supports are also very good. 2nd couple and 3rd couple acts good too. But I just pity the 3rd couple. They are not shown many times and their dating moment is only in 1 eps.
The thing I don't like from this drama: The ending is so unsatisfactory. The ending literally is a plot twist and it just ends IN a rewind.

overall, 8/10
