Yuichiro seeks revenge on the very people who killed his parents in a terrorist attack, but in return, he never once indulges himself in a moment of relaxation... until he meets the highly attractive courtesan, Mikaela. (Beta/Omega)

Mikaela Hyakuya has never been able to stomach the scents of anyone other than his family. For an unmarked, unmated omega, this is practically unheard of- lack of heat cycles from starvation be damned. Available omegas were supposed to crave the scents of viable mates, not be repulsed by them.

Mika is wearing a ring on his finger that can only be interpreted as something symbolic and Yuu takes notice of it.

Yuu attempts to have The talk with Mika only to get frustrated by his reactions. Mika is surprisingly oblivious.

Yuu should've died. But Mika saved him. In the future they have a treatment that allows dying people to live longer if another person's mind is transferred over to their body. Mika's mind is transferred over to Yuu's body so he can live, and will coexist with Yuu's mind until Yuu's body is able to live on it's own. When the time comes Mika will disappear as if he never existed.
