Become a father to a family for seven days.
Two years ago, Han Seol-eun's husband began coming home much later than usual and frequently returned heavily intoxicated.
Han Seol-eun chose to ignore it for the sake of family peace, not wanting to be suspicious.
But she couldn't help but notice. As the days passed, her husband came home later and later, and his clothes smelled of different women's perfumes every time.
Han Seol-eun endured it again for the sake of the family and for Han Seo-ah.
But this time, she truly couldn't hold back. There was a lipstick mark from another woman on her husband's shirt collar.
Han Seol-eun lost her temper.
She took the shirt to her husband, who was lying on the bed, and asked,
"What is this? What is this lipstick mark! I didn't say anything when you came home late or when I smelled other women's perfume on your clothes, but what is this?"
But her husband's response was calm and shameless.
"If you've been putting up with it, you should just keep putting up with it. Why are you so angry?"
With that, Han Seol-eun slammed the door and left the room.
For four weeks after that day, the happiness in the house vanished. Han Seol-eun and her husband lived without speaking, treating each other like ghosts.
One day, Han Seol-eun handed her husband an envelope.
When he asked what it was, she replied that they were divorce papers.
As if he had been waiting, her husband agreed to the divorce.
They went to court, and with the numerous pieces of evidence of infidelity Han Seol-eun had gathered over those four weeks, she naturally won the case after several months of legal proceedings.
Han Seo-ah went with Han Seol-eun, and the ex-husband was ordered to pay full child support.
