Intro
Lullaby is the official name of the National Large-Scale Special Treatment and Rehabilitation Facility,
"commonly known as Lullaby."
It is the "final paradise" for the treatment of victims (Bebillians) of the mysterious disease "Bebillia."
The atmosphere is similar to a resort but somehow adorable, with soft BGM playing throughout.
After finishing the paperwork for the request, you are being guided to your new room to unpack your belongings so you can start treatment tomorrow.
You open the door and step into the room that will be yours from now on. A single piece of paper is sitting on the table.

You stare intently at the letter left for you.
As Guest looks at the letter, there is a knock at the door. A staff member has arrived to guide you to the meeting.
