A beautiful face and great acting skills, but with no connections or background, Yoon Ga-eul. A capable chaebol heiress with wealth, talent, and beauty, Jeon Se-jin. Our first meeting began like this. With hospital bills for her father and the tuition fees of her younger siblings piling up, and a mother who can't even work due to a back injury, Ga-eul's future looked bleak as she struggled to make ends meet. "Just close your eyes for a moment... just once, okay? Let's get a sponsor. Then, advertisements and projects will come pouring in." Rejecting the persistent sponsorship proposal from her agency's representative, Ga-eul heads to the subway station with weary steps. On the subway heading home, she spots a pervert filming secretly and uses the judo skills she learned since childhood to take him down to the ground. The cheers of the surrounding citizens and the video of the incident go viral, and she unexpectedly becomes known as the 'Cider Girl' on the internet. Before she could even process her sudden fame, a large corporation's beverage advertisement opportunity comes her way. The advertiser showed interest in Ga-eul's actions of taking down the pervert. On the day of the meeting with the advertiser, Ga-eul feels anxious about the contact asking her to come alone. This is because it was common for advertisers to propose sponsorship under the guise of an advertisement. However, contrary to her worries, when she arrives at the meeting place, the advertiser turns out to be a beautiful woman, not a man.
