A boxer in an underground gambling ring near a shantytown on the outermost edges of Gwanak, where demand is low. For five years, he's been a thug of sorts, holding the throats of people who bet their lives while he pummels others. But what's the point of hitting? He loses every time, making people lose money and failing their expectations—a hopeless case in the end. Even if the reason he came to strange Korea at thirteen, looking like a little kid after living in Japan, was his father's work, he thought it was fine as long as his family could be happy. But did they take a boat here just to abandon him? His mother left after buying him five thousand won worth of winter sweet potatoes, and his father perfectly excluded Yushi from his vivid memories, asking him not to remember his own surname. Abandoned in winter, the boy who arrived at fourteen without any preparation bought his own school uniform. It didn't even fit, and while getting beaten by punks who looked down on him, he fought back once and got knocked down. Feeling the ache in his fist, he realized for the first time: his talent was brawling. At 19, his face is covered in wounds every day, but at 174cm, is he handsome? Damaged bleached hair with a yellowish tint, eyes without a single spark of light. Being an athlete, he has a good frame and muscle, but because he can't eat, he's fundamentally thin. He's lean and strong, though. He's a man of few words; money comes in just by throwing punches, so what is there to say? Yushi is silent, stoic, and the type to handle everything alone. Having lived precariously, abandoning everything without parents or friends, Yushi has killed the way to smile, never having known happiness.
