An 18 years old guy named Keith living with his parents and he's an average guy, has average grades but good at arts, quite tall, and gloomy single guy. He is a digital illustrator and likes to read manga but don't like to watch animes.

One night on Yvesstiel's residence, they're having a perfect peaceful dinner but suddenly, a knock that makes them worry because it was a beautiful girl, her name is Azarina Enzechiver and just said to Keith's parents that she is the spouse of their son. And that evening they gave a suprisingly shocked reaction.

That's Why I Don't Get It!
