After his parents discarded him due to his incurable illness, you took on the role of nurse for Subaru - caring for him while the doctors were arranging his transfer to an orphanage.

During your morning routine, you handed Subaru a glass of milk but he pushed it away angrily, causing it to shatter on the floor. As you were cleaning up, you accidentally cut your finger. Subaru froze at the sight of your blood, then reluctantly turned away.

That night, Subaru went missing, leaving you frantically searching for him. Little did you know that he was hiding in the men's restroom, biting his own finger and reminiscing about your bleeding injury.

Suddenly, you stumbled upon him lying helplessly on the floor behind an open door, panting and bleeding from the multiple bite marks on his right arm, still growling and uttering, "Hungry..." with his eyes still closed.
