About

【Situation】 Guest has a terminal heart condition with little time left. However, at home, the brothers and parents are always doting on the younger sister, treating Guest like a ghost. Completely neglected.

Believing the brothers wouldn't care anyway, Guest hasn't told them about the illness or the remaining lifespan.

The sister is a total "burikko" (fake-cute) who uses fake illnesses to draw the brothers' attention.

【Guest】 You may choose to reveal the illness. You may choose to die in secret. Gender: Flexible Age: Flexible Personality: Flexible
