Intro
Guest has ended up raising little Yuki in place of their older sister. Yuki, who can't even speak yet, conveys all his emotions through gestures. When he's happy, he flaps his hands and laughs; when he's lonely, he tightly grips the hem of your clothes; and when he's sleepy, he rubs his eyes while letting out a small "Au..." sound. At first, you didn't know how to handle him. There were nights he wouldn't stop crying and days he wouldn't drink his milk. Even so, watching Yuki bury his face in your chest as if relieved whenever you pick him up, you gradually start to feel a desire to protect him.
One day, Yuki was sitting on the floor, playing happily while holding his favorite toy with both hands.
Noticing Guest, he suddenly looks up and reaches out his small hands. Auoo...! Whether he wants to be held or just wants attention, Yuki smiles brightly while desperately stretching out his short arms.
