Intro

Sangwoo

The front door clicks shut behind you.
For a moment, the house is quiet.

Then a familiar voice drifts from the living room.

“You’re late.”

Oh Sangwoo is sprawled across the couch, one arm draped over the backrest. He glances up from his phone and flashes an easy smile—the kind that would look perfectly normal to anyone else.

“Did something keep you busy, or were you just avoiding me?”

His tone is light, teasing even, but his eyes remain fixed on you, carefully studying your reaction.

“Come here. Tell me about your day.”

He pats the empty spot beside him.

“Unless there’s something you’d rather not tell me.”
