Hua Jai Hor Bai Tong

This is the story of Nit, a hardworking and kind-hearted young woman. Her father, Non, has started a new family, causing the financial support he once sent to Nit’s mother, Sumon, to dwindle until it stops entirely. To ensure her younger brother Nui can pursue a high-level education, Nit decides not to continue her studies after high school. Instead, she enrolls in Sukhothai Thammathirat Open University (STOU) and spends her time helping her mother bake and sell traditional Thai desserts.
Theerachat, the sole heir to Chat, a famous businessman, is a highly sought-after bachelor. His mother attempts to arrange a match with Kingkaew, the daughter of a close friend, but Theerachat sees Kingkaew only as a sister. One day, while Theerachat is passing by Nit’s dessert shop, his driver asks to stop and buy some treats. After waiting for a long time, Theerachat decides to go inside. Upon seeing Nit, he is instantly struck by her beauty and kindness. He introduces himself as Khanmak, claiming to be a driver for a wealthy man, and begins finding various ways to stay close to her.
Eventually, Theerachat becomes a regular guest in Nit's home, and she happily accepts his friendship. Suddenly, Sumon’s dessert shop is sabotaged, causing sales to plummet and their finances to worsen. During this time, Nit delivers desserts to the shop of Prae, a former model she has known for a long time. Prae encourages Nit to try modeling, and Nit decides to give it a chance. Meanwhile, Theerachat investigates and discovers the sabotage was the work of Thip, an envious rival vendor. He secretly helps restore the shop's success.
When Nit travels upcountry to visit her father, Non is overjoyed, and Theerachat follows her there to introduce himself. However, the close bond between father and daughter infuriates Walee, Non’s new wife, leading to a heated argument. Later, Chat is rushing to the airport for a business meeting when his car gets stuck in the mud during a rainstorm. Luckily, Nit and Nui happen to pass by and help push his car out, allowing Chat to make his meeting on time. Chat is deeply impressed by their selfless spirit.
Chat tells Theerachat that there is a young woman he wants him to meet, but Theerachat refuses, stating he is already in love with someone else. Overworked and exhausted, Sumon collapses. Chat, who had come by to bring a gift as a thank-you to Nit, finds Sumon unconscious and rushes her to the hospital. While Nit stays behind to look after the house at her mother's request, Theerachat steps in to help Nit make the desserts. Seeing her devotion, he confesses his love and proposes marriage. Nit tells him he must speak with Sumon first.
In the end, Non divorces Walee after discovering her infidelity, giving him and Sumon a chance to reconcile. At the same time, Chat visits Sumon to officially ask for Nit’s hand on behalf of his son. Just then, Theerachat arrives for his usual visit. When he sees Chat, the truth is revealed. Nit is initially upset at being deceived about his identity, but Theerachat tirelessly follows and woos her until she finally understands his intentions and forgives him.
