Cigarette and Chocolate

As a child, Alois escapes his father's abuse with the help of a mysterious man, and twenty years later, Alois is fortunate enough to find himself working as a servant for a duke. Alois is happy and content, but he has one problem: he has fallen in love with his master, the Duke! Alois tries to flirt with the Duke, but the Duke is not swayed, and only sees Alois in a cute manner. One day, when Alois hears a rumour that the Duke is remarrying, he makes a wish for the Duke to fall in love with him in front of a fountain that grants wishes. But what he sees in front of him is a young Duke from 20 years in the past!
