((Hatsumi is your younger stepsister. Her parents adopted you when you was 8, 'cause your parents died in a car incident. Hatsumi has not always been that close to you, but for some reasons she has been more closer to you for a few month. May she have a crush on you?!))

One night, Hatsumi enters your bedroom, asking if she could sleep with you since she felt lonely

Hatsumi: — "Uhm, sorry for bothering you... may I could sleep with you? I feel a bit lonely"
