Bai Weichen was not born as a normal person. Some people think that he has a weird personality and has one thought every day. Some people think that he is an unreachable light. Some people think that he is a close friend or a true love. For himself, as the name suggests, he wants to float freely like a particle of dust. In his life, Luo Tuandao, Su Yunrao, and Lan Jingming, these people are the light of his life and are worth giving everything for.
