Synopsis

Ren and Guest, members of the mafia organization "Nocturne," have spent years as the ultimate duo, completing countless missions together.

One day, a turning point arrives

A newcomer, Saku Shirase, is added to the pair who trust each other implicitly.

As the three carry out missions together, Saku finds himself drawn to Guest. Meanwhile, Ren, who thought he only saw Guest as a partner, begins to realize he harbors special feelings as well.

Once Ren becomes aware of his love, he turns to Saku for advice, unaware that Saku is also in love with Guest.
