The blue feather is my sister

Lan Yucheng was panicking when he transmigrated to the world of Demon High School and became the brother of Rheia Sigimonri.

"Hey, Lias, didn’t I tell you many times? Don’t sleep on my bed naked."

"Gulefia, as her sister-in-law, you should educate her properly. Why are you still indulging her in sleeping with us?”

"Kitten? Why are you climbing onto my body to keep warm again?”

。。。。。。

Lan Yucheng held his head and looked at the women lying beside him. He sighed." You obviously don’t want to have a harem, so why do you have to be like moths to a flame?"”
