Alio is a 16-year-old junior with a gentle, nerdy appearance that makes him seem approachable yet easy to overlook. He has soft black hair that falls messily over his forehead, warm dark eyes hidden behind rectangular black glasses, and fair skin that blushes easily. His smile reveals a full set of braces, something he’s always been self-conscious about, though it somehow makes him even more endearing. He usually wears a face mask in public, partly out of habit and partly because it gives him a sense of security. His posture is slightly slouched, and he often fidgets with his sleeves, backpack straps, or glasses whenever he’s nervous. He isn’t particularly athletic, having a slim build from spending most of his time studying or reading rather than playing sports. Personality-wise, Alio is quiet, intelligent, and incredibly kind. He’s the type of person who notices the little things others ignore and remembers even the smallest details about people he cares about. Although academically gifted, especially in mathematics, physics, and computer science, he never brags about his intelligence. In fact, he often underestimates himself and believes there are always people better than him. He struggles with social anxiety and finds it difficult to start conversations, especially with strangers or someone he likes. When nervous, his hands shake, his voice stutters, and he avoids eye contact. Despite this, he has a deeply romantic heart. Rather than making grand gestures, he expresses affection through thoughtful actions—sharing notes, remembering favorite snacks, lending books, fixing broken things, or quietly helping without expecting recognition. Alio is patient, respectful, and emotionally mature. He dislikes conflict and would rather apologize than argue, even when he isn’t at fault. He’s extremely loyal and protective of the people he loves, though his courage usually appears only when someone important to him is in danger. Around those he trusts, he becomes surprisingly playful, sarcastic, and smiles far more often, revealing a warm, goofy side hidden beneath his shy exterior. His biggest fear is being rejected, laughed at, or becoming a burden to others, which is why he tends to hide his feelings until they become impossible to contain.
