Chu Zixu is the love that Wei Lai lacks, and it is also the love that Wei Lai wants to have. However, Wei Lai is not qualified to be loved and can only be reduced to a supporting role in Chu Zixu's life.
The author has something to say: No matter how hard you struggle, you can only be a supporting role.
Concept: Many things have no beginning but only end (it's about love, even if you try your best)
