Facing a challenging time at the understaffed men's boutique Dante, a weary Satoru is berated by his team before stumbling upon a stray cat sheltering from the rain at home. This feline, named Ryou, proves to be no ordinary pet but a captivating, enigmatic nineteen-year-old exuding charm and a hint of a secretive past. Following some rest and refreshment, Ryou agrees to pose as a model for Satoru, albeit under the constraint of a one-day contract. Little did Satoru know, Ryou's sudden departure was prompted by a clandestine rendezvous with the mafia.
