Some people's love is very strange, such as Cheng Lin. He loves someone, but is only that person's friend, just like a movie theater audience, that person's life is being shown in front of his eyes but he is unable to participate. But Cheng Lin felt that maybe this was the best love.
When the movie comes to an end, when everything comes to an abrupt end, Cheng Lin still loves that person. Although he has been labeled as "best friend" his whole life.
In life, there is always one person who is the only shining point in all the ordinary things. The light fades, who am I?
