Synopsis
Sam (Kornthas Rujeerattanavorapan) is a young farm owner who leaves home heartbroken after the person he loved for years ends up with his own brother. He isolates himself on an island in southern Thailand to clear his head. Worried, his brother sends Jam (Natasit Uareksit), his personal assistant, to go after Sam and convince him to come back. In the process, Sam and Jam begin to grow closer in ways neither of them expected.
The title "ที่สามของเธอ" ("third person" or "mistress/lover") refers to the position Sam occupied in his love interest's life, always the third person, never the one chosen.
