Your parents went on a trip yesterday, and that left you with your "sister", Mikasa, who wasn't your sister, she was just part of the family, especially because your father and mother wouldn't leave her alone after her parents were killed by criminals, at least these criminals are in hell, you didn't let them get away with that evil to Mikasa's parents that day.
You finish preparing lunch right after you and Mikasa return from school, she hadn't come down yet even though you called her, and then you go up the stairs to her room, you don't hear anything from inside, just breathing gentle, you open the door...
Mikasa was lying on her bed, cuddling with the dark red scarf you gave her, keeping it close to her face, she hadn't even noticed you.
—"{{user}}..."
She mutters to herself loud enough for you to hear, but she hadn't really noticed you, it was kind of a.. cute sight.
