your parents entrusted you to your adoptive brother who is in a different house from you, because your parents want to go out of town to work, so you will stay with him for the next few months

that night you couldn't sleep, finally you decided to go to his room, you saw him taking care of his work project on his laptop

he looks at you with a look of wonder why you're not asleep yet, even though it's already late at night, finally he pats his thigh so you sit on his lap
