In the eleventh episode of Dynamite Kiss, Da-rim's undying love for Ji-hyuk is laid bare after her heroic rescue from the fiery ordeal. As they're about to embrace in a passionate kiss, Gyeong-min and the paramedics make an unexpected entrance, momentarily dampening the romantic vibe.
Gyeong-min goes overboard with his concern for Ji-hyuk's well-being, but thankfully, our swoon-worthy hero is unscathed, especially after that heartfelt confession. Meanwhile, Tae-young and Ji-hye meet for drinks to celebrate their successes, with Tae-young seemingly envious of Ji-hyuk's accomplishments without his father's assistance. Ji-hye agrees to join forces to eliminate Ji-hyuk from the company.
At Ji-hyuk's abode, Gyeong-min, still oblivious to the love triangle, pleads with Ji-hyuk to be kinder to Da-rim. As expected, Ji-hyuk is in a euphoric state, reminiscing about his first encounter with Da-rim and the blossoming romance between them. The same sentiment echoes in Da-rim's mind as she tosses and turns in bed, consumed by her heart-racing moments with Ji-hyuk.
The next morning, Ji-hyuk wakes up on cloud nine, dancing as he prepares for work. Da-rim also puts in extra effort to dress up for the day with In-ae's assistance. At the office, they steal moments in the elevator before Ji-hyuk sends Da-rim a bouquet of flowers, promising to make her happy. Her colleagues gush about Seon-u being a sweet husband, prompting Ji-hyuk to get jealous and order them back to work. Later, he tells Da-rim that the flowers mark their first day of dating, though he pretends to be scolding her while secretly asking her on a date. Their colleagues misunderstand and feel sorry for Da-rim.
On the professional front, Ji-hyuk attends a meeting where Ji-hye blames the fire incident on a different company dealing with labor management issues. However, Ji-hyuk insists on a more detailed investigation into the culprit. Later, he visits Ha-yeong and obtains CCTV footage of the incident.
Elsewhere, Seon-u imbibes a few drinks with Da-rim, but when he senses she might reject him, he abruptly ends their meeting. The next day, Ji-hyuk and Da-rim indulge in a lunch date away from the office's prying eyes. Unfortunately, their romantic sojourn is cut short when they spot their work colleagues looming. Ji-hyuk is forced to hide, while Da-rim joins the others. As the day draws to a close, Da-rim offers to stay back and assist Ji-hyuk in sifting through old company files. Ji-hyuk is helping his mother gather the necessary documents for her upcoming divorce.
As they delve into the documents, they realize that In-ae is a formidable woman. Da-rim takes this opportunity to console Ji-hyuk, reminding him that he is no longer alone. Her words deeply resonate with him. Upon returning home, Da-rim prepares to break Seon-u's heart, but he suddenly claims it was all a prank. Da-rim is taken aback but accepts it.
At Ha-yeong's house, her mother is busy preparing her for the wedding. Ta-young shows up, pretending not to know who's behind the fire mishap. He insists that Ha-yeong drop the issue, but she explains that Ji-hyuk is looking into it. Later, she drops by Seon-u's place to inform him of the exhibition's success despite the fire's ruinous aftermath. She comforts him after noticing his sadness over Da-rim's rejection, promising to wait for him as he navigates his emotions.
At NaturalBebe, Ji-hye convinces Chang-ho to allow the MotherTF team to support the CS team. This is all part of her master plan to overwhelm the team and eliminate them. She and Chong-gu deliberately set up the team to take the most challenging and trying customer calls. The transition proves daunting for the team, but they refuse to give up. Go-eun confides in Gyeong-min, while Jin-hee turns to retail therapy to get through the day.
Later, Ha-yeong pays a visit, playing the dutiful fiancée of Ji-hyuk in front of Chang-ho. Da-rim, envious of her role, is invited by Ha-yeong for a drink. As they talk about Seon-u, Ha-yeong shares her determination to win his heart. Her warm sentiments melt Da-rim's heart, and they end up getting drunk, calling Seon-u and Ji-hyuk to pick them up. The scene is hilarious as the two men struggle to bring their girls home. Yet, Ji-hyuk is proud to be the man Da-rim calls when she gets drunk. They take the two drunken women to Da-rim's place. Later, Seon-u and Ji-hyuk have an honest conversation. Ji-hyuk promises to take care of Da-rim and love her right.
In the morning, Ha-yeong volunteers to help Seon-u take care of Jun. The little boy excitedly agrees to be her best friend and shares his pain of not having a mom. Jun has an upcoming school event, and Ha-yeong asks him more about it.
At the office, the MotherTF team prepares for another difficult day. Unfortunately, Da-rim becomes embroiled in a scandal when an overwhelmed mom calls to complain about finding a chicken bone in a diaper. Da-rim tries to calm her down, but the woman lashes out, posting a scathing post online with a fake voice recording. Chong-gu and Ji-hye decide to use this opportunity to get rid of her. Ji-hye ups the stakes by involving her media contacts. A group of angry mums and reporters show up at the company to protest. Da-rim tries to explain her side of the story but they attack her, throwing flour-powdered diapers at her. Luckily, her team arrives to protect her.
Ji-hye and Tae-young watch the show from afar, plotting their next move to expose Ji-hyuk's affair with Da-rim. After learning what happened, Ji-hyuk quickly returns to the office to take care of Da-rim. As soon as they are alone, he embraces her in a warm hug. Da-rim opts to talk to the woman behind the scathing post, and Ji-hyuk insists on going with her. Initially, the woman, So-yeong, refuses to talk to them. However, she changes her mind when Da-rim sacrifices herself to save So-yeong's baby as her stroller accidentally rolls downhill. Thankfully, the baby is unharmed, and Da-rim sustains only minor scratches.
Later, the woman takes down the scathing post and reveals the truth about the incident. The MotherTF team also works on getting rid of other disparaging articles online. After successfully solving the problem, Ji-hyuk and Da-rim celebrate with the team. Just as Ji-hyuk suggests a team dinner, Ji-hye disrupts their celebration with a revelation: she shows Da-rim's certificate of marital status, which shows she is unmarried.
