Kuroneko to Waltz
黒猫とワルツ
Hirose is furious after catching his boyfriend Matsui cheating again, this time with the flimsy excuse of wanting to see a girl's breasts over a guy's penis. Heartbroken and enraged, he goes to a nearby shrine and curses Matsui out of sheer frustration.
The next day, Hirose discovers a black cat with a scar identical to Matsui's waiting outside his apartment. Strangely, Matsui has vanished without a trace. As Hirose takes in the cat, he begins to suspect a bizarre connection between his missing boyfriend and the mysterious feline, leading to an unexpected and complicated living situation.
