Khun Phor Jam Pen (Accidental Daddy)

Four fraternal quadruplets are secretly left at the doorstep of Arthit, a carefree playboy and songwriter, at different times of the day: morning, late morning, afternoon, and evening. This leaves Arthit with no choice but to take them in as their foster father. He names the children Arun-chao (Morning Dawn), Tawan-sai (Late Morning Sun), Bai-pela (Afternoon Time), and Napha-yen (Evening Sky). To afford raising the kids, Arthit is forced to rent out his large house to foreigners and moves the family into a small rented house in the Soi Ruam Samakkhi community.
In this neighborhood live Chuenchob and Chaichom, the children of Auntie Chuan, who runs a local noodle shop. Chaichom is a soldier stationed at the northern border and knows a secret regarding the kidnapping of children from high-ranking families, who were smuggled across the Salween River into Thailand before mysteriously vanishing. Chuenchob, on the other hand, is a teacher. When Arthit enrolls the four children at her school, she mistakenly assumes they are his biological children and that he is a widower.
Later on, a group of street children wanders into Soi Ruam Samakkhi, much to the disgust and rejection of the local residents. Arthit and Chuenchob team up to help protect these homeless kids from danger and find them foster homes. Through their shared efforts and teamwork, their relationship gradually blossoms into love. However, Kwandee, a woman who has her sights set on Arthit, becomes fiercely antagonistic toward Chuenchob. Meanwhile, the quadruplets—Chao, Sai, Bai, and Yen—adore Chuenchob and actively root for her to marry their father.
The situation takes a complicated turn when strangers suddenly appear, claiming to be the children's parents. Arthit and Chuenchob struggle to verify whether these people are telling the truth, sparking a series of chaotic, hilarious, thrilling, and tear-jerking events surrounding the children's dilemmas.
Eventually, the true parents of the four children reveal themselves—they are individuals of high noble status who possess undeniable proof of their parentage to Chao, Sai, Bai, and Yen.
What decision will Arthit make? And how will Arun-chao, Tawan-sai, Bai-pela, and Napha-yen react, now that they deeply love their "accidental daddy"?
