Ai wo Kataru nara Hisoyaka ni

This is the story of a cold-hearted mafia and the strange relationship he shares with the maid who works for him. In truth, he's actually a gentleman who is infatuated with his maid! From buying expensive gifts to planning the perfect date, he does everything he can to express his love—almost like he is unaware of the difference in their social standings. Thus begins a flashy, fun, and slightly dangerous romantic comedy.
