Mark is a charismatic engineering student who won the annual popularity contest on campus. This coveted title has given him a confidence boost for his already overinflated ego. Mark is best friends with Wayu, a sweet and gentle guy from a wealthy family. Currently, Wayu is in a committed relationship with his boyfriend Pha. They are happily in love, and their cute romance is the envy across campus.

Pha is a medical student. His best friend is Kit, one of the top students in his discipline. When Wayu and Pha invite their friends for a meal, Mark becomes smitten with Kit. However, the feelings are not mutual. Kit is turned off by Mark's swagger and finds his flirtatious behaviour annoying. Mark is aware his crush doesn't like him. However, that only strengthens his resolve and he keeps hitting on Kit.

After making a lousy first impression, Mark steps up his game and hopes to win over Kit. He'd wait outside the campus building for a chance to interact with his crush. However, his sincere efforts have not moved Kit, who remains irritated by him. Kit openly antagonizes his suitor, unwilling to respond to any romantic gesture. Nonetheless, Mark is tenacious and continues his courtship despite the multiple rejections.

Kit has a close relationship with his younger brother Phai, currently in his final year of high school. Phai is friends with Wayu's younger brother Sab. They begin an apprenticeship program, working at the café. Their classmate and coworker Sandee seems fond of Phai. However, Phai remains oblivious of his crush and treats him platonically. Thanu is one of the regular customers at the cafe. Despite never meeting each other, Thanu and Phai develop a mysterious connection over their serendipitous encounters.

Phai, Sab, and Sandee go to the same high school as Pok and Tong. Pok is on the swim team, vying for a sports scholarship as his ticket to university. However, his grades aren't the best. In contrast, Tong is one of the best students with top grades. Phai asks Tong for a favour to give Pok tutoring lessons. As they study together, ambiguous feelings develop between the two high school students. Yet, their relationship takes a dark turn when Tong receives an unpleasant surprise.
