One Year 365

One Year 365 (Thai: 365 วัน บ้านฉัน บ้านเธอ; RTGS: 365 Wan Ban Chan Ban Thoe; lit. 365 Days - My Home, Your House) is a Thai family drama television series produced through a collaboration between GDH and LINE TV. The series tells the story of two families who are required to live together for one year under a condition centered on happiness, exploring themes of love, understanding, and emotional growth. It premiered on LINE TV from 28 November 2019 to 6 February 2020, and later aired on Channel One 31. The series stars Katreeya English, Sanya Kunakorn, Jirayu La-ongmanee, and Cherprang Areekul, along with seven members of the Thai idol group BNK48.

Tum, a widower with two children, decides to propose to Mook, a widow with four daughters, after their relationship becomes serious. However, Mook has not informed her children about the relationship. To introduce both families, Tum arranges for his children to meet Mook's daughters during Mook's birthday celebration. The meeting immediately creates tension, particularly between Petch, Mook's eldest daughter, and Baby, Tum's younger child. When Petch learns of Tum's proposal, the children are shocked and briefly run away from home.

After returning, Petch proposes a condition: both families must live together for one year, and if any member is unhappy, the relationship must end. Mook and Tum agree, and the families move in together. The trial period is marked by frequent conflicts, especially between Praewprow, Mook's youngest daughter, and Baby. A serious incident occurs when Baby gets lost, leading Praewprow to run away and live with Phum, Mook's ex-husband. At the same time, Phailin, Mook's third daughter, who left medical school due to academic pressure, openly rejects Tum's presence and later leaves the house as well.

While tensions persist, some relationships improve. Praewprow and Baby reconcile and begin to accept each other as siblings. Subplots develop, including a complicated romantic triangle involving Petch, Boom, and Tawan, as well as a secret relationship between Ploy and Mark, a famous actor, which later becomes public and leads to their breakup.

The situation reaches a turning point when Phailin learns that her father has become distant due to his new wife's pregnancy. Hurt and disillusioned, she runs away to live with her girlfriend. Tum searches for her, gains her trust, and helps her reconcile with the family. Despite this progress, conflicts among Petch, Boom, and Tawan cause the one-year agreement to collapse. In accordance with the condition, Mook ends her relationship with Tum, and both families separate.

Over time, unresolved feelings and misunderstandings are gradually resolved. Petch and Boom reunite after confronting their emotions honestly, and fractured relationships within the household are repaired. In the end, the two families come together once more. Mook marries Tum, and the extended family is finally able to live together in harmony.
