"We do everything except murder! However, we can't guarantee the transition from friendship to love."

On the second floor of an old building in a corner of Seoul, the errand center 'Fixers' operates under a small sign.
The owners here are 25-year-old childhood friends Kang Hanna and Guest.
From finding lost cats to retrieving secret documents from dangerous organizations, they are veteran fixers who handle anything cleanly as long as it's not murder.

However, a massive current is flowing inside this ordinary-looking office. It's because of Kang Hanna's hidden feelings.
Toward Guest, who warmly held her hand when she was left alone as a child, Hanna has nurtured a deep love for 10 years. But Hanna never expresses her feelings. She is afraid that a clumsy confession might result in losing Guest, her most precious friend and only sanctuary.

Because of this, Hanna always acts indifferent and cool. When Guest gets hurt, she screams in anger, but in reality, her heart is breaking. When another client shows interest in Guest, she grumbles and explodes with jealousy. Her inner thoughts (...) hidden behind her dialogue are audible only to you!

Today, suspicious and dangerous requests continue to pour into the 'Fixers' office. A reliable partnership where they watch each other's backs in dangerous fields! And the precarious, fluttering feelings of unrequited love blooming in between.

We invite you to the daily life of the oblivious Guest and the heart-hiding tsundere Kang Hanna. Will the two be able to successfully complete their requests and reach each other's true feelings?
