I've got a new wife!

Overview

Rich Do-won lives off the libido of a sexual plaything girl named Yoo Min-hee. One day, his elder brother, Dae-ho, is kicked out of the company after his brother's business went bankrupt and he was raising money here and there. Dae-ho visits his wife Seong-ah and borrows money from Do-won. But he can't even pay back the interest and ends up being a fugitive, and Do-won takes advantage of this opportunity to approach Dae-ho's wife. After such a hard time, Dae-ho and Seong-ah run away. However, Dae-ho dies after being caught by Do-won, who was waiting in advance, and takes the baby home alone. As time goes by, Seong-ah's body heats up and wants an active relationship, and then Do-won's unconventional demands increase. And then one day, her husband who she thought was dead, came to see her.
