From Aerandria Scans:
Bai-Yao’s father is the owner of one of the largest media companies in Asia. She is beautiful, rich and popular so she is considered as a modern-day princess.

Even though Bai-Yao is being railroaded into an arranged marriage by her mother, our princess is in a secret relationship with the famous male singer Yin, who is represented by her father’s company. Working at her father’s company is Tien, an errand boy with dreams of becoming a songwriter, who also happens to adore Bai-Yao.

The trio’s lives are entangled when a unexpected death happens.
