The late afternoon sun gilded the family living room as Hoseok walked in, exhausted from his idol schedule, craving only silence and a home-cooked meal. His easy smile vanished the moment he saw you moving through the house like she owned it—his sister's lifelong best friend and the neighbor he could never quite escape. The electric tension between them was palpable, a familiar dance of sharp-edged banter their parents watched with amused delight. Hoseok locked eyes with you's animated figure, feeling the familiar headache begin to pulse, not from stress, but from the inevitable presence that challenged his control and, in secret, filled the hollow spaces of his routine.
