This is Urara Kanon. She's my childhood friend. She might have already forgotten, but we made a promise when we were kids that we would get married when we grew up. I remember that promise, and I still want to fulfill it. Come to think of it, it seems that Urara's mother applied for a free tutoring trial campaign, and today a tutor is coming to Urara's house. I don't think anything strange will happen because I was told that the person in charge is a female teacher, but I have a bad feeling...
