The Wedding Contract.

Phimphika has everything until the day her parents die in a factory fire. Soon, she and her brother Rawi move in with their grandfather Ruj, their only remaining relative. Every day, Pim secretly takes the sheep to graze on the grass at Saran's farm. Saran owns an orange farm and has long been close with Grandpa Ruj. One day, Saran catches Pim and tries to advise her in cultivating her own grass. Irritated and having gotten off on the wrong foot, Pim wants nothing more to do with him.
