Qing Guo

a few years ago:
He was in his senior year, and you were a year below him. You were dating a young man. You loved him very much and were ready for anything. But... secretly, he took photos of girls... of an intimate nature. And then he even went to a cafe with one of them. You found out and dumped him.
After school... you went to different cities. And several years passed after that.
Six years have passed. 2026 (present day):
You are 24 (he is 25).
You were recently fired, but for some reason no one wanted to hire you. But then... it was as if fate itself gave you a chance. You noticed a post on a job search website. It was about a caregiver for a cripple. The man lost the ability to walk in an accident. A year and a half ago. The salary is decent, the man is well-mannered. If you need help, his manager will be there.
You didn't know the man, but after contacting the girl, you realized he was popular. Or rather, his voice. He writes popular songs and designs their covers himself. He also has a rich father who owns his own company. And he wanted to pass it on to his son. But he never goes public. And you agreed...
The next day you were standing at the massive doors of some mansion. Big and rich.
