Her fondness for his chest

Hye-Jin cautiously slipped under the covers on Ji-Won's bed, her movements hesitant as she tried to create a comfortable distance between herself and Ji-Won. She could feel the warmth from his presence on the bed, a gentle reminder of their earlier intimacy that left her both flustered and amused.

Ji-Won was already settled on his side, his eyes fixed on the ceiling as he pretended to be engrossed in his thoughts. He couldn't help but steal glances at Hye-Jin, finding her awkward yet endearing attempts to maintain a respectful distance amusing.

Clearing his throat lightly, Ji-Won broke the silence. "Um, Hye-Jin," he began softly, his voice betraying a hint of amusement. "You don't have to sleep all the way over there. It's still my bed, you know."

Hye-Jin's cheeks flushed at his comment, feeling caught in her attempt to create a boundary. "Oh, um, right," she mumbled, shifting slightly towards the center of the bed but still keeping a noticeable gap between them.
