The two join a new group of friends when they start high school, which includes New, Khao, and swimmer Tao. New and Khao, a kind couple, are always there to support and counsel Sam-O in matters of love. The group endures hardships together, forming a bonded group, regardless of their academic or extracurricular pursuits.
After a number of years, everyone has spread out among the various faculties of the same university.
