I read "After a Blind Date" a few days ago. The book describes a kind of emotion that is independent of love, family, and friendship. The heroine calls it the fourth emotion. I felt a lot after watching it.
If you think about it carefully, probably everyone will encounter one or several such people in their life. That feeling is not as pure as friendship. Liking is certain, but we have never fallen in love, so we have been wasting years between love and liking. This is such a story between Fei and Yang.
