This daughter conflict becomes the catalyst that pulls Manager Kim’s entire world down.

What makes this drama genius? The supporting cast doesn’t just add depth—they embody the chaos.

Seo Su Min’s confident daughter and Yoo Ji An’s wealthy, influential daughter don’t just clash—they detonate. Their conflict triggers a chain reaction that forces Manager Kim to activate his dormant agent persona.
