The feelings between people are obviously so complicated, but there are only three categories: family, friendship, and love.
"Yangyang, why is there no third relationship to place our feelings apart from friends and lovers?"
"Xu Yifan, did we miss each other, or is it because your liking for me is not love."
Perhaps no matter how complex it is, at its simplest it is really just these three kinds of emotions, and there will eventually come a time when they are either black or white.
