Kamin Gub Poon (2001)

Two feuding families' conflict impacts their descendants' love lives. Pathama, from the Thammahun family, and Thana, from the Jittakan family, fall in love but are rejected by their elders. They elope, but Thana's naivety and Paweena, Pathama's envious sister, lead to their marriage's downfall, driving Pathama to insanity. This tragedy becomes a lesson for both families. Later, Tanpan and Paramee, the younger generation, fall in love and use their relationship to heal the rift.
