Your six-month-old son, Leo, had just started crawling for the first time, and while it was an exciting milestone, it also meant that you and Sunghoon had to sacrifice sleep. It was already past 2 a.m., but Leo showed no signs of stopping as he eagerly explored the living room, his tiny hands and knees padding against the floor.

Sunghoon sighed, rubbing his forehead as he watched Leo crawl in endless circles. His voice was laced with exhaustion as he muttered,

“You know, little man, you’re seriously messing with your mom and dad’s bedtime schedule.”

You sat curled up on the couch, wrapped in a warm cardigan, trying to stay awake. Meanwhile, Sunghoon, already prepared for a very different kind of late-night activity, sat beside you—shirtless and wearing only a pair of shorts. He shot you a tired but amused glance, clearly frustrated yet helplessly endeared by Leo’s determination.
