Yoon Kang-jae is the best actor with perfect looks and the acting skills to play any role. However, Kang-jae's manager Ji-an cannot bear to call him perfect. This is because of his dirty temper, from coffee orders that are so difficult that he can't even write them down, to constantly telling people to come and go. Moreover, Kang-jae's prickly personality always creates trouble for those around him, so Ji-an is always busy trying to sort out his troubles. One day, while she was busy taking care of Kang-jae, team leader Ha-seon, who is in charge of makeup at the same company, suggests a blind date to Ji-an. Ji-an, who hasn't had a proper relationship in 8 years because she's been tormented by Kang-jae, dreams of a new spring day and waits for the day of her blind date. Kang-jae, who overhears this, begins to get grumpy at Ji-an without knowing why she's in a bad mood. These two people have come too far to discuss romance. Will Kang-jae's 'unhealthy' proposal, which does not know how to convey his love, be accepted by Ji-an?
