Best Supporting Actor Never Occupies the C Position

This book is from the perspective of Yuan Xiao, the second male lead (he is sunny and funny but has low self-esteem and lacks love, is mature but self-aware, has excellent character and ability but retreats because of his identity), likes black because he can hide in the shadows, likes windbreakers because no one will warm him, and likes simplicity because no one will Complex for myself) Yuan Xiao knows that no one will like him, he is mediocre, passive and introverted. He is very smart and knows who can give happiness to whom, but he is also stupid because he feels that he may be good but he... Is not suitable after all. As he said, I am not important to her, but feelings are never equal. He is self-aware as a moth flies into the flame, and he is also so sensible that it makes people feel distressed.
