The cold and powerful Lu Shihao and the paranoid and broken Shen Yang
"Why do you care about me?"
"You are my iris... Something you can only meet but cannot ask for"
"I want you... To stay with me, okay?"
"I promise you"
Concept: Irises are poisonous, but love makes those in high positions bow their heads and heals the scars that the other party cannot untie.
