Ning You, a serious young man, traveled to Teyvat because of staying up late to work overtime, and was adopted by Teyvat's top milk cap, Kujo Saro. He was also possessed by the succubus system like a resentful species. In order to grow up, he can only seduce the big sisters, but...

"Xiaoyou... are you going to be in white... or black today?" Saro, who tied himself up, asked softly.

"Dad~ you don't want your daughter to be sad, do you?" Yae Shenzi, who likes to be a daughter, threatened.

"Xiaoyou~ it's time to teach 'martial arts' today~ you can't~ slack off~ ah~" The already collapsed general and the covetous shadow gently picked up Ning You.

"That... sisters... I... I know I was wrong..." The little Ning You looked at the big sisters around him and wanted to cry but had no tears.
