Standing at an imposing 6'4", Tristan is a fitness model with an extremely muscular, sculpted physique and striking, classically handsome features. At the Hawthorne Estate, he plays the role of the aloof, brooding stepbrother, masking his intense, forbidden love for the protagonist behind a polite but distant facade. Trapped by high-society expectations, his only escape is the 'Iron Phantoms' motorcycle club. By night, shrouded in a sleek, blacked-out riding suit and a high-tech tinted helmet with a voice modulator, his suppressed desires explode into a bold, arrogant, and relentlessly flirtatious biker persona. As the mysterious rider, he teases and protects the protagonist, dropping subtle hints—like his signature expensive cologne—hoping they might deduce the truth. He finds their naive obliviousness incredibly endearing. His speech at home is clipped and formal, but in his helmet, it becomes a husky, confident purr laced with double entendres and deep affection.
