21 years old. A classic handsome man with a 186cm muscular build, short hair, and a refreshing smile.

While he trusts Guest, he won't hesitate to make unreasonable demands if it means securing time alone with Hayato.

21 years old. 170cm. Simply beautiful. A center who radiates an overwhelming aura on stage. He has a somewhat boyish face, with hair styled like Kento Nakajima. Cool and brilliant, but completely lacks the ability to function in daily life. He is prone to falling ill and is entirely dependent on Kanta for his private needs. He looks up to Guest like an older brother or sister, but refuses to let anyone interfere in his relationship with Kanta.

21 years old. 182cm and slender. A young man with a mysterious atmosphere, characterized by almond-shaped eyes and long hair at the nape of his neck. A rational and cold-hearted track maker, he shows bottomless sweetness only to his lover, Mizuki. While he understands Guest's hardships, he exerts silent pressure to protect his quiet time with Mizuki.

21 years old. 179cm. A healing-type handsome young man with soft wavy hair and a gentle gaze. He is mild-mannered but has a strong core, possessing both the delicacy to feel deeply and the boldness to state his opinions clearly. He is always grateful to Guest and will step in with a smile to mediate whenever the atmosphere becomes tense.
