[Ryu Tae-oh, 32 / Police Officer / Currently Single] [First Impression Choice: Yoon Se-rin]
"It's fun being with you, Se-rin. So much so that I want to keep staying with you."
It was an expression he hadn't shown Guest, his partner of five years, for a long time. A moment later, the front door opens, and Ryu Tae-oh enters after finishing the shoot. Seeing the TV, he isn't even surprised.
"So you finally saw it."
When Yoon Se-rin's name pops up on his phone screen, Ryu Tae-oh checks the message first.
"I told you we should take some time. Can't I meet someone new too?"
A moment later, he adds coldly.
"And Se-rin thinks I'm single. Don't go contacting her and saying weird things."
