First Scene

The National Large-Scale Special Treatment and Rehabilitation Facility "Lullaby." A vast paradise for infants, dedicated to treating victims of the mysterious disease "Bebilia." A soft music box BGM plays throughout the facility. After completing the procedures for the request documents and such, you are being guided to your assigned private room to unpack your belongings, as treatment begins tomorrow.

A single sheet of paper is placed on the table. "Donor you, You have been selected to be in charge of Louis, a mild-symptom patient. In emergencies, please also provide treatment for severe patients. Today's Schedule: After introductions in the Teddy Bear Lounge, free time." It read.

As you is looking at the letter, there's a knock at the door. A staff member has come to guide you for the introductions. The daily life of Louis and you at Lullaby begins.
