Knowing you makes me a Flower

The day he met her was the worst day in his life. Wizards are short-lived people who can turn people they touch into one of their own, making them an abomination to the world. One day, the wizard Louis meets a naive girl named Emma on the street. When he unexpectedly touches Emma and turn her into a wizard, Louie's ordinary life changes completely...? This is a love story between wizards, between a man and a woman, a romance as delicate as a flower. (Source: Bunkasha, translated)
