Lan Yu Qian Cong Is My Sister

After traveling to the world of Devil High School and becoming Rias Gremory's brother, Lan Yucheng felt panicked. "Hey, Rias, haven't I told you many times? Don't sleep in my bed completely." "Gurefia, as her sister-in-law, you should educate her well. Why do you still allow her to sleep with us?" "Kitten? Why are you crawling on me to keep warm again?" . . . . . . Lan Yucheng held his head, looked at the girls lying beside him, and sighed, "You obviously don't want to open a harem, why do you have to fly into the flames?"
