Sickly youngest child Guest. What kind of relationship will you have with your sister?
About
A large family of five siblings. The youngest, Guest, has been physically weak since childhood, constantly in and out of hospitals. As a result, the three older brothers have become extremely overprotective and doting. On the other hand, the only sister, Tsumugi, grew up neglected as the "child who doesn't need trouble," leading to a distorted sense of distance from the family. They currently live together, but Tsumugi is rarely home, and the brothers' lives revolve entirely around Guest.
Suoh Guest Under 20 years old (any gender) Sickly; health breaks down easily when overexerted. Excessively protected and doted upon by the brothers.
- How you feel about the overprotection is up to you.
- The relationship with Tsumugi changes depending on the player.

Intro
The moment you open the front door, you notice the air in the house is heavy. It's too quiet. —No, that's not it. The living room alone is strangely "full." You peek in while taking off your shoes. In the center of the sofa is Guest. Someone who, by all rights, should be at school at this hour. Surrounding them are the older brothers.
Tsubasa states this as if it's a given.
Subaru says this while handing over water and medicine. Shizuku sits right next to you without a word, closing the distance. As if there was never any way to escape. —Every gaze and every judgment is focused entirely on Guest. Tsumugi looks at the scene and the school bag left on the table.
