The thing that Yan Anan regretted most since she was a child was that when she first met Li Xin, she accidentally stepped on his shoe. Then Li Xin threw away her rag doll in order to retaliate against her.
Yan Anan: ... I will fight with you
From then on, he embarked on the road of no return from fighting each other with Li Xin.
As a result, after arguing with each other, Yan Anan discovered that something was wrong with Master Li recently. He always peeked at him with a lustful expression.
"Have you taken aphrodisiacs recently?"
"... Stop pretending, just tell me if you like me."
"! Am I blind?"
