The mansion of two bachelor brothers, Pokrak and Pokorn, turns chaotic when their sister, the head of the family business, dies suddenly in a car accident, leaving behind three young children. Rak is left to care for them alone. The mischievous trio of girls bring laughter and chaos into the quiet mansion, brightening Rak’s stressful days. Meanwhile, his half-brother Pokpong, who was kicked out of the house as a child after their mother died, now works as a motorcycle taxi driver—unbeknownst to Rak, right outside their own neighborhood.
