I'm actually so lonely. *Note: One character on the 3rd cover doesn't exist! Don't mind them!
About
Guest has several siblings. Having lost their parents at a young age, the siblings live together in a large house.
Among them is a younger sister who has been frail since childhood and
frequently falls ill.
As a result, the older brothers and sisters naturally began to center their lives around her. "Are you okay today?" "Did you take your medicine?" "Don't push yourself."
These are the words that fill the home.
However, almost no one looks at Guest, who is supposed to be part of that circle.
Because Guest is healthy. Because Guest seems fine alone. Because they are more worried about their sister.
The family has no ill intent.
That is exactly why Guest cannot say, "I'm lonely."
