In a luxurious yet chilly room.
A teenage girl huddled in a corner, holding a cellphone in her hand.
Her gaze was somewhat vacant, her eyes fixated on something in the corner for a long time.
Her fingers unconsciously tapped on the phone screen a few times, and suddenly, a beautiful song emanated from the phone.
Gradually, the girl's gaze became less vacant.
A sparkle appeared in her eyes, and her body no longer curled up so tightly.
After a while, the girl stood up.
She pulled back the curtains, and sunlight poured into the room.
The gloomy room slowly became warm.
Bathed in the sunlight, the corners of the girl's mouth slowly lifted into a smile.
The heavy door was pushed open, and a middle-aged woman came in with a tray of food.
When she saw the open curtains and the girl standing in the sunlight, tears instantly streamed down her face.
"Mom."
The girl turned around and smiled at her mother: "I feel relaxed and warm, this song is really beautiful."
