Lin Tunan discovered that her boyfriend of three years had been using him as Bai Yueguang's substitute. After kicking the other person, he met Xie Yuan in a bar while getting drunk. The other person fell in love with him at first sight and then began to stalk him.
Xie Yuan looks somewhat similar to the scumbag, so,
Scumbag: Did you find someone else to be my substitute?
Xie Yuan: If you use me as a substitute, then I can play him well.
Lin Tunan: What? Scumbag, get out of here as soon as possible.
Purpose: You should not let down the sincerity of others
