Before meeting Yu Anche, Han Ranyi thought that he would be alone forever. His appearance would unsurprisingly save Han Ranyi's soul.
Yu Anche: I knew he was such a person. I... I... I just don't like him that much, hum!
Han Ranyi: The thoughts he had hidden for so long were discovered so easily by this child. This child seemed to be an angel sent by God to save him. Such a small one gave him all the sense of security. "Yu Anche," Han Ranyi never expected that this name would become the existence that haunts him throughout his life.
Purpose: Mutual redemption
