Young-sim's career is on the line. She gets one chance to keep it alive by taking on a pilot reality dating program. She uses all her power and connections to find the right guests. Miraculously, one of them is a high-profile CEO of a startup company, and he turns out to be the childhood friend who left her waiting on a park bench twenty years ago.

One of the female guests gets into an accident and can't make it to Young-sim's show, causing chaos. Without any other options, Young-sim steps up and takes her place. However, she still isn't sure if Wang Kyung-te is the Kyung-tae she once knew as she faces him.

Young-sim's pilot dating program becomes a hit. However, she becomes the laughing stock for getting zero points. While she tries to deal with her embarrassing image, a bombshell leak about the final outcome causes outrage and tarnishes Kingvely's reputation.

Kyung-tae pulls through and determines to restore Kingvely's image by agreeing to do another dating program with Young-sim. Young-sim might still have animosity toward Kyung-tae, but it's her only chance to save her career. However, an unexpected situation arises when she meets with Kyung-tae to share the program's proposal at his house.

Young-sim and Kyung-tae get caught in a pickle, almost naked. Chae-dong and Wol-sook sense something strange between them and vow never to leave them alone together. Meanwhile, the team meeting for Young-sim's new program with Kingvely goes nowhere, and Wol-sook suggests going on a work retreat.

Things get a little tipsy and revealing at the work retreat. But Kyung-tae shows his knowledge in dating and wins everyone's hearts. Out of Kyung-tae's chaos, Young-sim thinks of a brilliant idea for the dating program and calls it "Love, Mark." They pitch it to the director with high hopes.

Kyung-tae and Chae-dong chase after Ki-ho, who took off with the footage and Young-sim. They catch up and save Young-sim and persuade Ki-ho to let his episode go on air. Young-sim returns the favour and finds someone else who would gladly meet Ki-ho on a blind date.

Min-ji and Woo-chan's episode begins filming, but Kyung-tae's personality gets in the way. As Young-sim and Kyung-tae try to make things work between Min-ji and Woo-chan, they can't help but realize the similarity to their brief childhood romance. Meanwhile, Woo-chan learns what happened in the past, and Young-sim goes on a date.

Young-sim and Kyung-tae fall deeply for each other. Despite their happy days as a couple, another incident occurs that tests their relationship again. Wol-sook schemes to make reporters write articles that say she and Kyung Tae are dating. Although Kyung-tae wants to get the facts straight, Young-sim sees this as an opportunity to promote her show.
