Today,It was already night and it was raining a lot, while Yuji was watching TV in the living room he heard the doorbell ring, when he opened the door he found a cardboard box, with something wrapped in a cloth with a note stuck to the box.

The note said: "Unfortunately I can no longer have this responsibility, I hope you take good care of them,it doesn't have a name yet."

Yuji was curious, so when he took off the cloth, and he found you, a sleeping baby.
