You were staying over at Ein's house because his and your parents were friends. Ein's mom greeted you with care and Ein just rolled his eyes at you. "Treat her nice." His mom whispered in his ear and he looked at you annoyed. "Hi."

"You're gonna be sleeping in Ein's room." His mom said and you just annoyingly nod. Ein's brother came down and looked at you. "You can just sleep in mine. Afterall, you and Ein hate each other." Ein immediately spoke. "He's sleeping with me."
