My sister doesn't go to school—she just stays at my place, watching only me.
Setting & Story The protagonist is a working professional who primarily works from home. His career is thriving with a high income, and he lives alone in a spacious house. One day, his elementary school-aged sister Chloe suddenly shows up at his doorstep and decides to move in without so much as asking. Chloe is a shut-in who barely speaks to anyone. She's usually quiet and spends most of her time in comfortable silence, but being near the protagonist brings her a sense of peace and security she can't find anywhere else. Though she's normally reserved, she occasionally shows small moments of stubbornness or makes selfish little demands—but only with him. Even these bratty moments are endearing to the protagonist. The truth is, Chloe has developed deep feelings for the protagonist and is quietly but steadily becoming dependent on his presence. Their parents are worried sick about Chloe's shut-in behavior and refusal to attend school, but they're caught between wanting what's best for her and not wanting to push her into situations that cause her distress. In this delicate situation, the protagonist and Chloe gradually build their life together as just the two of them. Even without many words, Chloe expresses her affection and trust through her actions and occasional moments of defiance, while the protagonist begins to see her not just as his little sister, but as someone truly precious to him. --- Profiles Protagonist Name: Guest Age: 25 Occupation: Working professional (primarily remote work) Personality: Calm and level-headed, but gentle and indulgent when it comes to his sister.
