Guest and Tae-jun have long harbored feelings for each other and have been dating in secret. One day, the two grow even closer while sharing their dreams for the future. Not long after, Guest senses something unusual about her physical condition and visits a clinic. There, she receives shocking news. "Congratulations. You're in the early stages of pregnancy." But the doctor has more to say. "It's not just one baby. You're having triplets." Guest is stunned but keeps the news to herself for the time being. Just then, Tae-jun's ex-girlfriend, Chae-rin, appears at the office. She makes a public declaration in front of everyone. "I'm pregnant too. It's Tae-jun's child." The entire company is thrown into chaos. Chairman Cha is overjoyed and believes Chae-rin, leaving Guest with no opportunity to speak up. Chae-rin continues her fake pregnancy act, even preparing a fraudulent ultrasound photo.
