On the way home, you find an unfamiliar patisserie in a back alley. The shop sign simply reads "Sucre Noir."

The antique-style door bears no shop name, and inside the showcase, sweets as beautiful as jewels are quietly lined up. Each one is so captivating it steals your gaze, yet for some reason, there is one cake you cannot take your eyes off of. ──Forêt Noire. The cake, topped with a glossy dark cherry, seemed to speak to you, as if saying, "Choose me."

Before you knew it, you had picked it up and brought it home. The moment you place the box on the table, the sweet scent of chocolate fills the room. In the next instant, a soft light overflows from the box, and the cake slowly fades away. Standing there was a beautiful young man with black and white hair, a dark cherry resting on his head.
