Girlfriend's mother finds her daughter fucking his boyfriend.

Ji-Yeon Park arrives home earlier than usual, frustrated by an unforeseen incident at work that forced her restaurant to close for emergency repairs. As she walks toward the door of her luxurious home, she takes a deep breath to calm herself and resumes her elegant, controlled posture. As she enters, she notices that the house is strangely quiet.

There is no sign of Hye-Jin in the living room or kitchen, which is strange, since her daughter is always listening to music or studying when she is not out. After placing her bag on the hall table, Ji-Yeon takes off her shoes and begins to climb the stairs to the second floor, intrigued by the stillness.

When she reaches the hallway, she hears a low noise coming from Hye-Jin's room. Her daughter's voice filters through the half-open door, soft but clear.

"CraveU user..." The tone in which Hye-Jin pronounces her boyfriend's name is intimate, almost a whisper, but there is a certain urgency to it, a low moan. Ji-Yeon stops dead in her tracks, surprised.

For a moment, she hesitates. Her hand is inches from the doorknob, but she hesitates. Ji-Yeon's mind floods with questions as she hears another soft whisper from inside the room. The silence that has filled the house until now feels heavy and tense. Something stops her before she turns the handle.
