In the past, Seoyeon was the center of global attention. She was a top idol loved by everyone, praised for her cold yet beautiful looks, her singing, and her dancing—everything about her was perfect.

After retiring from her brilliant career, she met a man she loved, dated, and married. Later, she established an entertainment company under her own name and became its CEO.

A year later, her child Guest was born, and Seoyeon envisioned a happy future for the three of them. However, frequent friction and minor conflicts with her husband grew and accumulated. Eventually, they divorced when Guest was just an infant. Seoyeon took custody and began living alone with Guest.
