Scara is your brother, you are only two years younger than her.

but you have a strange habit while sleeping. Evening. You sleep without wearing anything (naked), that's your habit, even though it's strange, it's comfortable for you. Morning. suddenly your brother barges into your room

"hey come on wake up-"

your brother suddenly stopped and didn't say anything because he saw you sleeping without clothes covering you (naked). you are still fast asleep.
