I'm into a youth drama so I decided to write a review about this one.
If you're looking for a short drama that talks about School/Youth/Friendship, you can pick this one.
This is quite interesting and not boring at all. The simplicity of life during 1990's make it more interesting for me.

But this drama is too short that I want to raise some question like:
How/When Mingyu happened?
It's because the flashbacks only end to their High School party. What happened to the relationship of Zhao Lei and Lili is a big question for me. When did they have a son? And why Lili raised him alone for 16 years?
