Dopamine follows the lives of ten university students and how they deal with life, romance, and everything in between. Wayo hasn't gone out of his room for months, isolating himself because of a painful past. Aside from his family and his best friend, there is only one person he's comfortable socialising with. Will that person be able to convince him to come out of his comfort zone? How is he going to cope with the outside world? And what would he feel when the person who made him feel safe and protected is a part of his past, except he is unaware of it? Arthit, a head hazer who tends to overuse his power, finds himself oddly drawn to a certain first year student who does nothing but fluster him and get on his nerves. Out of spite, he gives him a task so ridiculous that it backfires. What if the attraction he so tried to push away comes crashing down at him? Being a Medicine student, Beam has always wondered how the SOTUS system works. When he and his friends chance upon an ongoing gathering, it piques his interest and takes a peek, inadvertently catching the interest of a hazer. Kit, a cranky teenager who seems uninterested in everything, offhandedly comments about some school gossip which involves two male students. It seems harmless at first until he is unable to stop thinking about "the tall guy on the right". Rome has always been a good son and a loving brother who puts everyone first before himself. But when he gets in a minor accident and meets the person who caused him pain and injury, he figures it's about time to finally get what he wants. And he wants that Engineering student bad.
