How to Use Guys with Secret Tips

A self-help video called "How to Use Guys with Secret Tips" has reached Choi Bo-na (Lee Si-young), a woman worn down by work whose standing with men is going nowhere. The lecturer on screen is Dr. Swarski (Park Young-kyu), and the tips arrive with a straight face and total confidence. Lee Won-suk lets Bo-na sit in front of that video, watching the doctor's face, the lesson plan still waiting to be tried.
