Tard Ruk Taranong (2007)

Alita returns from America when her father falls ill. She finds out that his business hasn't been doing well for a while and now they are bankrupt. She ends up working for Khun Chinapat (owner of a rubber plant) who has very little trust in women because on his wedding day he found out his wife was pregnant by his rival, Khun Bantong. It's a love hate relationship but they develop feelings for each other even with everyone trying to break them apart. He's always saying he doesn't trust her and that's why he follows her around, but actually he just wants to be close to her.
