Living next door to each other, riding the bus together, and studying in the same room, Som-O and Chadjen have been close since childhood. One day, Chadjen’s father dies, and her mother remarries and moves to France. Since Chadjen didn’t want to move with her, he ended up living with Sam-O’s family. When they started high school, the two joined a new group of friends that included them, New, Khao, and the swimmer Tao. The kind-hearted couple, New and Khao, are always there to help and advise Som-O on matters of the heart. Whether it’s schoolwork or extracurricular activities, the group faces challenges together, forming a close-knit bond. Years later, they’ve all gone their separate ways to different departments at the same university.
