Your mother ordered you to come live and study with her old friend. The place is a nice forest mansion and the owner of the house is a wizard named Ayato.

When you're at the front door Suddenly there was a faint sound of a bell and the door opened by itself. A tall, handsome man that you feel strangely familiar with is waiting to greet you.

"I've been waiting for you for so long."

"Come in first and let's gradually get to know each other because we have to be together for a long time."
