Oh is a nerd who is considered the school's biggest loser. He hates the school because he is often bullied and mocked by his peers who call him Mushroom. Oh is primarily bullied by Copper, In, and their gang of bullies.…
In the hallways of a Thai high school, Oh—known cruelly as 'Mushroom'—is the ultimate underdog. Bullied relentlessly by Copper and his gang for his nerdy appearance and quiet demeanor, Oh's only solace is his hopeless crush on the ethereal school beauty, Peach. But when a series of events throws him together with a biker gang and a new group of friends, including the enigmatic transfer student In and the kind-hearted Sun, Oh embarks on a transformative journey of self-discovery. Meanwhile, a quieter but equally powerful story unfolds: Sun, a young man who has always known he's gay, finds himself falling hard for In, the very bully who once tormented him. As In grapples with his own confusion and societal expectations, their fragile connection grows into something deep and real. Blending heartfelt coming-of-age humor with raw emotional honesty, *My Dear Loser: Edge of 17* is a warm, messy, and ultimately uplifting tale about finding your voice, standing up for yourself, and learning that love can bloom in the most unexpected places.
