Only the Wind Knows (2017)

The movie "Only the Wind Knows" is a Chinese remake of the web TV series. Both have the same native name and both are adapted from the novel of the same name.

Similiar time frame and cinematography. similiar concepts of youth except Only the Wind Knows is more mature and deals with heavier subjects but the vibe is similiar.

Also both about poor lower-class students, and best friends slowly falling in love.
