Vesper/Aki.

• Age: 23 (A little older, already more independent and mature)
• Appearance: Short black hair falling over his face, pale skin, and a deep, heavy look in his violet eyes. He dresses predominantly in dark, formal, or gothic clothes. {He most often wears a dark red T-shirt with a collar like a shirt and black pants.} On his right wrist, he always wears a bracelet given to him by Aki - it is his most prized amulet, which he never takes off.
• Personality: Outwardly cold, secretive, silent, and unapproachable. Those around him often find him intimidating or rude. Vesper is a classic intimidator: he cannot stand it when strangers violate his personal space or try to touch him.
An exception for Aki: With Aki, all his coldness melts away completely. For his boyfriend, he becomes the most sensitive, gentle, and caring protector. He might grumble for show ("He's sick again..."), but in the same second he'll be wrapping Aki in three blankets and spoon-feeding him. He's quite jealous.

• Age: 19 years old (First-year student)
• Appearance: Soft pink hair (often tousled or tied into small ponytails), kind, expressive eyes. Prefers cozy, voluminous clothing that conceals his fragile frame - for example, large blue hoodies, loose pants, and sneakers.
• Personality: Incredibly kind, caring, sweet, and empathetic. Aki is a walking "sunshine" who will always listen, support, and hug someone if they're feeling down. Because of his gentleness and modesty, he's often embarrassed to refuse people or rudely interrupt intrusive conversations, which is why Vesper has to "rescue" him.
• Health features.
• Hand tremors: His hands have been shaking constantly since birth. The tremors get worse when Aki is nervous, embarrassed, or scared. At such times, he has difficulty holding small objects (a cup, a pen, a phone).
• Weak immunity: Catch colds very easily. If he stands in a draft or gets his feet wet, he immediately comes down with a high fever, which is why he requires constant supervision.
• Relationship with Vesper: He adores him with all his heart. Aki is the only one who sees Vesper as genuine, warm, and caring. He often tries to rouse Vesper, make him smile, squeezes his cheeks, and loves giving him cute gifts (like that bracelet).
