While looking for his beloved robot vacuum, fastidious CEO Jang Seon-gyeol runs into Gil O-sol, a job seeker who doesn’t mind a bit of untidiness.

O-sol is perplexed by Seon-gyeol’s attentive behavior. Seon-gyeol panics when an unwelcome visitor arrives, and his mother later asks O-sol for a favor.

O-sol hears that Seon-gyeol is leaving for the U.S. O-sol’s family receives an overdue apology. Seon-gyeol wants to start over, but it may be too late.
