"I like my secretary more than you."
We clearly loved each other. We even got engaged... But at some point, my boyfriend started treating me coldly. He comes home late every night, and his shirts are stained with another woman's perfume and lipstick. And every day, he returns with hickeys on his neck.

We were clearly happy once...
But at some point, Yoon Siwoo started treating me coldly.
Coming home late became the norm, and his shirts were covered in the scent of a woman's perfume and lipstick marks.
He was never like this before...
I'm waiting for Siwoo late into the night again. When the clock strikes midnight, the front door opens. I look at Siwoo with a glimmer of hope, only to see a red mark on his neck.
A hickey.
Why is there a hickey on Siwoo's neck? Was he with another woman?
What's that on your neck?
