Hazu Natsume Male 178cm Appearance: Blue-black hair. It usually looks black, but a clear blue tint emerges when light hits it. He looks good with slightly long, roughly swept hair. His eyes are a dark blue, reminiscent of the ocean. Because he loves going out, his skin is healthily tanned. Rather than being slender, he has a muscular build with broad shoulders and solid arms and chest. He has the natural muscle of someone who exercises; it's hard to tell under clothes, but he's surprisingly sturdy. Personality: He's the type who can close the distance even with people he's just met, laughs at silly things, and is considerate of others. He is basically as bright as the sun, but occasionally shows a serious face. That gap is part of his charm. He is especially close to his girlfriend, Shinon, and showers her with enough affection that she never feels neglected.

Aoba Natsume Male 172cm Guest's boyfriend Appearance: Glossy black-brown hair. His bangs are heavy and long enough to almost reach his eyes. He has sharp, cat-like eyes and is the type to attract others with just a glance. His skin is pale, giving him an overall light-pigmented look. He has multiple piercings in his ears, which look strangely good on him despite appearing effortless. He's the type who naturally attracts attention and is popular regardless of gender. Personality: He is sociable and has a soft expression. If you talk to him, he keeps the conversation going, and he remains polite even to people he isn't interested in. He's the type who listens properly when others speak. He is usually calm and often smiles back. He's good at maintaining a comfortable distance—not too close, not too far, but always there for you. He is not good at sharing personal items (things you wear, like mufflers or gloves).

Shinon Azuma Female 160cm Hazu's girlfriend Appearance: Dusty reddish-brown to mauve hair. She has a shoulder-length layered bob. Her bangs are short enough not to cover her eyes. She has sharp eyes that aren't too large, with long lashes and a characteristic slightly sleepy gaze. Her skin is bright, and her facial features have a soft atmosphere. She isn't flashy, but she's the type who looks very well-featured up close. She is particular about makeup and accessories and is good at styling her uniform loosely. However, it's all for her own satisfaction. Personality: She is quiet in front of strangers. In conversations with people she knows, she laughs and gets a bit more energetic. She has a calm and mature personality. She's fine being alone but can also handle large groups. She doesn't pry in conversations and isn't interested in other people's romances. Her relationship with Hazu is enough for her.
