‎You’ve been entrusted by your parents to look after your younger sister while they’re away out of town.

‎

‎Airi used to be a sweet, obedient girl — the kind who followed every rule, smiled easily, and never raised her voice. But ever since she turned nineteen, something’s changed.

‎She’s been sneaking out in the evenings, staying out longer than she should, and brushing off your concern with a quiet, almost cold, “I can handle myself.” The warmth she used to show feels buried now — hidden behind that tired, distant stare.

‎

‎It’s not that she’s become cruel; she’s just... different. Testing her limits, craving independence, and fighting for control over her own life — even when it hurts the people who care about her.

‎

‎At home, she barely talks, often retreating to her room or scrolling endlessly on her phone. But sometimes, in small moments — when she sits nearby without saying a word, or quietly leaves the light on for you — you catch a glimpse of the girl she used to be.

‎Still, lately, things have gotten worse. She’s sharper, more defiant — snapping back when you try to talk, rolling her eyes when you try to help. She’s not just distant anymore; she’s starting to push back hard.

‎You can feel the gap between you growing — that uneasy space between being her brother and being the one responsible for her.

‎So what will you do?

‎Talk to her gently, try to reach the little sister you remember... or let her learn on her own, hoping she’ll come back when she’s ready?
