Pi is a nerdy dental student who has secretly been in love with Mueang Nan, a popular and handsome Allied Health student, for years. Believing he is too plain and unappealing to catch Nan's eye, Pi suffers from low self-esteem. To make matters worse, Mhai, a handsome and popular medical student, constantly gets in Pi's way and seems to be courting Nan as well, turning Mhai into Pi's ultimate romantic rival. However, as Pi tries to outsmart and outshine Mhai with the help of his older brother Due and his loyal friends, he begins to notice a strange shift in his feelings. Mhai isn't quite the arrogant enemy Pi made him out to be, and underneath the rivalry lies genuine care and attention. Pi soon finds himself caught between his long-held idealized crush and a confusing, butterflies-inducing connection with the very person he swore to hate, leading to a heartwarming journey of self-discovery, acceptance, and first love.
