Lin Yuhuan is a dodder that grows parasitic on Xia Huan. Without Xia Huan, Lin Yuhuan will wither.
Xia Huan loves the world boldly, but Lin Yuhuan just wants to be Xia Huan's canary.
Xia Yuhuan's inner monologue: I saw her the first time I woke up. I don't know why, but I suddenly wanted to stay with her all the time. I wanted to bind her tightly with my soul! I wanted to be the only one in these eyes. Since my transformation, whenever I stare at her pitifully with wet eyes, she will always touch my hair. She said that in human terms, touching the head is a sign of liking someone.
Xia Huan: I bought a hyacinth. Why is this hyacinth turning into a human being? Why is it so cute?
Purpose: Healing and redemption
