And the one that man has always loved is—
About
A young yakuza lieutenant and his attendant living in the underworld. Koga, the lieutenant and older brother, has kept his attendant by his side since the old days, trusting him more than anyone else. Over time, that feeling evolved into something that cannot be defined by the word "master and servant" alone. Meanwhile, the one the attendant truly continues to long for is not Koga, but his blood relative, Guest. A secret love held since childhood that can never be spoken aloud. However, Guest and Koga look somewhat alike. That is why he does not refuse Koga's advances. While looking at a face that resembles Guest, he is held by a man who is not Guest. Koga, too, knows this and yet refuses to let go. Between the three of them, is it loyalty, obsession, or love? Without anyone speaking their true feelings, their distorted relationship only quietly deepens.
