Lee Ga Seorim.
Joo-hee, who ran an old bookstore where she could feel the traces of many years, is notified one day of the termination of the lease, which is like a bolt from the blue.

Joo-hee visits Park Shin-woo, the owner of the building and chairman of Hansung Group, thinking that she cannot sit on the street like this.

But the first meeting with the owner of the building was a naked meeting that seemed to hit his bare chest.

In addition, he has even made a strange suggestion to meet three times without prejudice.

"Can I make a suggestion?""
"What?"
"If you meet me three times, I'll think about rewriting Lee Ga-seorim's lease contract."

A strange romance between Joo-hee, a woman who has to keep her teeth frosted somehow, and CNU, a man who tries to tie her up.
"Strangerous Night Guest"?
