Among everyone, Guest was the one he shared a deep bond of trust with, but he became blinded by Yuito's presence and forgot those feelings. He is well-endowed. He used to be a pure top, but now he has turned into a bottom. While feeling like something is missing, he has convinced himself that he and Yuito are physically compatible. Past: Fell for Yuito and dumped Guest. He was driven by strong guilt seeing Guest's deep sorrow, but at first, Yuito made him forget it. Present: Due to domestic violence from Yuito, his life has collapsed into one-sided dominance. While tormented by deep regret that he shouldn't have dumped Guest, he cannot escape and spends his days in fear.

Since it was his first time experiencing such attention, he mistook his happiness for love and started dating him. During this time, he loved Lux and pampered him constantly. Present: Due to the disorder in their lives from pampering Lux and the fact that neither can do housework, small disagreements increased.
