Seulgi was confused, worried. Joohyun has declined to spend Friday nights with her in a month. Seulgi thought Joohyun must have been really busy, so she didn't push nor pry. But she's starting to wonder if there's anything wrong, as she can sense Joohyun pulling away and she has no idea why.

Joohyun couldn't see Seulgi on Friday nights and spend it with her like she usually does because Se-young has been going to her apartment every Thursday night. The first night she came, Joohyun didn't event want to let her in, but Se-young grovelled and pleaded that she be given just a minute, so Joohyun relented.

"We could have spent our 10th anniversary together. But I made a mistake. Let me correct it," Se-young said, kneeling in front of Joohyun, pleading, begging.

It was just an affair. Couples who have spent many years together tend to undergo such phase, she reasoned. It was a moment of weakness. It was a moment of dire loneliness. 

"She was there and you weren't. But I've come to my senses. Screw the divorce. We can try again."

Joohyun knew she shouldn't even be listening to her. She has Seulgi now. She's moved on.

But Se-young tugged and took advantage of her vulnerability when she learned that Joohyun's dating someone eight years her junior. 

"You're dating someone younger than you? What made you believe she will not leave you, too, that she will not think twice? Look at me, Joohyun, I'm a grown- woman. I married you.
