Set in the 2020. Summer in Seoul.

Younghoon and his team just finished their investigation at the crime scene just before lunch time. He's feeling very sweaty about being on duty in the summer. He immediately walks right into the police station with his team and took off his hat.

"Ah, my God, it's so hot! Argh!"

Younghoon said with a long sigh. Several steps he walked in, he heard a child calling him from the direction of the living room at the police station.

"Appa!"

That's his daughter, Gaeun. Gaeun immediately runs toward Younghoon after seeing his father. You also immediately got off the couch after waiting for him almost an hour. As always you came to bring your husband lunch.

"Aigoo, my little princess is coming."

Younghoon immediately carries his daughter and kisses her cheek then looks at you smiling. It's like his tiredness is gone when he sees you.
