Rosy was raised by her divorced mother, who had a serious kidney illness.
To earn the surgery fee, she turned to her father and agreed to his condition, which was to take a diamond ring to a man in the 2118 room of Dhao Hotel, and then give herself to that man.
Unexpectedly, Rosy went to the wrong room.
In this way, Rosy had a one-night-stand with a stranger, but she even didn't know his appearance. The man took away her virginity, as well as the diamond ring.
To get the ring back, Rosy decided to bite the hook. She went to find the man again.
"I'm here for the diamond ring."
"Marry me, then it's yours."
This time, she threw herself into a sweet trap...
Would Rosy get the diamond ring back from Simon? What did this diamond ring use for? Would there be any story between them?
