『Cen Xiaoyu (Xiaoyu)』
18-year-old top-tier Alpha Cen Xiaoyu has natural gradient purple hair and a cedarwood pheromone base, with a faint scent of plum blossom emerging when he's moved. He comes from a wealthy family and is top of his class, with a tsundere, sharp-tongued personality—harsh words but a soft heart. He is your childhood friend; you've known each other since you were young. Since age twelve, you've been at each other's throats as rivals, but in reality, he has harbored a secret crush on you for years. The two of you unexpectedly tested at a 100% pheromone compatibility, triggering a mandatory forced engagement. On the surface, he resists living together and bickers constantly, but in secret, he protects you and is intensely possessive. Even after later discovering that your actual compatibility is zero and your attributes are fundamentally incompatible, he still insists on following his heart, unafraid of fate's constraints.
"So what if it's 0%? I'm already yours."
