Season 1

Woo Hyun once had things going for her. During that time, she had won the award for excellence and dreamt of becoming the best home shopping host at UNI. However, Ok Sun gained all the recognition, and slowly, Woo Hyun's career started to take a step back to the point of selling toilet paper. Now, she yearns for her comeback and approaches their rival home shopping network for a job.

Mo Ran holds out her hand to Woo Hyun, who is in despair, and offers her help to turn the tables. However, Woo Hyun finds Mo Ran's complete change in attitude suspicious. Meanwhile, comments mocking Woo Hyun's failed attempt in transferring to Gaon Homeshopping surface on the company's anonymous bulletin board. With her mind in a mess, she ends up ruining the show and goes into hiding.

Mo Ran senses that Woo Hyun would remind Hyun Wook of his past love, Hae Soo, and sets up a dinner for them to meet. Woo Hyun catches on quickly to the intent of the meeting, becomes humiliated, and leaves. But soon, she appears before him, soaking wet in the rain. Meanwhile, a mysterious shadow behind Ok Sun's perfect image while she helps In Guk campaign begins to show.

Woo Hyun comes back to sell out show after show in place of Ok Sun during prime-time slots after meeting with Hyun Wook. Mo Ran explains it was the direction the company wanted, but surprisingly, Ok Sun shares what's been on her mind with In Guk. Meanwhile, Mo Ran becomes deep in thought after receiving a message from James, a young international student, and Woo Hyun has a deep conversation with Hyun Wook on a brisk walk at her location shot.

Ok Sun visits an orphanage with her son, Jung Hyun. As she solicits a confidential request from the orphanage's director, she shows a deadly side to her character. Meanwhile, during the after-party at the location shoot, Sung Woo gets drunk and confronts Mo Ran about the accident she witnessed, and Woo Hyun gets scouted by the rival network that refused her transfer. Later, Woo Hyun approaches Mo Ran with a bold proposal.

Woo Hyun wants her proposal to launch a cosmetic company in her name with her husband, Do Il, as a co-CEO to get underway. However, Mo Ran has other plans and urgently orders Joon Bum to do something that makes him think twice about following it. Meanwhile, Woo Hyun prepares to start her new show with An Na, who Mo Ran planted to keep watch over her.

Although Mo Ran is furious about Joon Bum going against her direct orders, she unexpectedly leaves Hyuny, the company under Woo Hyun's name, in his hands. Do Il attends Hyuny's launch meeting as the CEO, and he becomes wary of Joon Bum. Meanwhile, Ok Sun plans to have dinner with Mo Ran, In Guk, and Jung Hyun. However, behind her amiable intentions lies something profoundly deep.

Ok Sun becomes furious after secretly listening to In Guk and Mo Ran's conversation and begins the revenge she has kept inside for over ten years. Meanwhile, Woo Hyun's Hyuny cosmetic line launches. However, the promotional sample causes skin problems on the influencer's face and becomes a disaster. Do Il, who was in charge of the samples, disappears. Without any options left, Woo Hyun asks Mo Ran for her help.

Hyun Wook charges at Mo Ran angrily regarding Hae Soo's ring. Making things worse, he sees Woo Hyun on her knees. Before he gets an answer, Mo Ran, who is already in a weak state, collapses. Later, Do Il appears in front of Hyun Wook and confronts him violently. And James shows up in front of a weakened Mo Ran, who takes him to her house. However, everything James does, gets relayed back to Ok Sun.

Ok Sun lets In Guk know about her revenge. In Guk is shaken by Ok Sun's fierce demeanour, and Mo Ran speeds up her plans of establishing a subsidiary as soon as she gets wind of Hyun Wook's counterattack. Meanwhile, Woo Hyun finishes up her first show with Gaon but soon finds out Hye Rim betrays her at the hands of Mo Ran and tells everything she's been hiding to Hyun Wook.

Ok Sun violently tells Mo Ran about the past she knew between her and In Guk but gets even angrier when she tells her she never once betrayed her, whom she thought of as a younger sister. Meanwhile, Hyun Wook opens up after hearing Woo Hyun's confession and prepares a way for her to come back to UNI Homeshopping. As Woo Hyun's comeback show turns out to be a success, Mo Ran rushes to see Sin Ae and threatens her with a secret about her past for her shares in the company.

Hyun Wook, who has now fallen helplessly from knowing how Sin Ae killed Hae Soo, gets comforted by Woo Hyun. Woo Hyun bravely faces Sin Ae, who would do anything to stop anyone after her husband, and challenges her to the fight. She tells Do Il that she wants a divorce and says she loves someone else. Meanwhile, Ok Sun obtains shares in UNI Homeshopping from James and tells Mo Ran about his true identity.

Mo Ran finds out that Jung Hyun is her son and asks In Guk, in uncontrollable confusion, how the adoption came to be. Meanwhile, Ok Sun, who now has a considerable stake in UNI Homeshopping, begins to take control. She scraps Woo Hyun's show and gets Mo Ran suspended. Later, Hyun Wook finds out about Mo Ran's deepest secret as she recovers in the hospital.

Hyun Wook gives Woo Hyun some time to think after his sudden marriage proposal. Meanwhile, In Guk faced a crisis in his political career due to Ok Sun's disclosure of his affair, and Jung Hyun, who figures out it was Mo Ran from the description in the article, warns her not to hurt his mother, Ok Sun. Later, Woo Hyun figures out Ok Sun's true colours when she sees her about her shows getting cancelled. She also realizes she was just a pawn in Mo Ran and Ok Sun's battle for their desires.
