Tine is a first-year college student and self-proclaimed playboy who has a gay admirer in his university named Green. To get Green to leave him alone, his friends convince him to make Sarawat, an attractive but introverted guitarist and soccer player, his fake boyfriend. After his first attempt to pursue Sarawat fails, Tine joins the music club, where Sarawat is a member. Eventually, Sarawat agrees to Tine's offer. The show then proceeds to follow the ups and downs of their "fake relationship" which eventually blossoms into a real relationship, but not without the usual problems of jealousy and insecurities that come with dating.

Note: 2gether is an adaptation of JittiRain's Phro Rao Khu Kan novel series.
