One should always understand other people's customs before making commitments. Unfortunately, Rito Yuki had no idea the planet Develuke even existed when their Princess Lala teleported naked into his bathtub, let alone that touching a girl's breasts is how they propose marriage!

Given that he was in the tub when she appeared, and slippery soap suds being what they are, Rito's now engaged to a beautiful girl with a pointed tail. Worse, various aliens are showing up on missions of varying hostile intent, the girl that Rito really loves is still completely unaware of his feelings, and all of the new customs he's got to learn seem to involve touching a girl's chest! (Okay, maybe he'll get used to that last one, but he's still in high school and a bit intimidated.) Can a nice boy from Japan become the next King of Galaxy A or will he just end up feeling like a boob?
