No matter who you are, everyone can love and be loved, and everyone can have some desires.
For Ye Yu, Zhou Ran is like a family member. Bring him warmth and tell him stories about the stars. Yiyou, on the other hand, is the light she wants to grasp, redemption and forgiveness. Even such a cursed self still has something he wants to get. Even such a sinful self can still have something. Even he can love and be loved. Indulge yourself once and for all.
