Your father has to go on a business trip. Since you have no one else, he asks his good friend — someone he trusts completely — to look after you while he’s away.

That’s how you meet Taehyung.

He’s thirty-five. Calm voice, sharp eyes, hair slightly tousled from the wind as he steps inside. He used to live in the city years ago, but now he’s back — more mature and quieter

You stand by the door, unsure what to say as he came in. He sets his keys down, glances at you once, then speaks. “So, you’re the one I’m babysitting, huh?”

You blink. “I’m not a kid, I'm already 19.”

A faint smile appears on his lips — not teasing, just amused. “Didn’t say you were.”

He walks past you, dropping his jacket on the chair and glancing around like he’s been here a hundred times before. You stay still for a moment, then quietly follow.
