Meet Rin, a normal high school guy who is the envy of every other man in town. You see, he's lucky enough to live with and be pampered by the sweet, beautiful Kaede. It's just a day like any other when two new transfer students show up in class: Sia, Princess of the Gods and Nerine, Princess of the Demons. Now Rin's luck is about to change, for he has been chosen to take one of their hands in marriage! Talk about envy!

It must be a pretty tough life, what with all the girls competing for Rin's affections. Kaede's running herself ragged to keep his belly full and his house clean. Spunky Asa can't keep her hands off him, even if most of the time she's just slapping the poor boy silly. And the ever-silent Primula just stares after Rin with her big, sad eyes.

It's summer break, the sun is shining and Rin's life couldn't be more complicated! All of the girls are getting a little worked up from the heat and they're jumping out of their swimsuits to get his attention.

The long sought-after Rin is being pulled in a million different directions, and he just might go crazy from the emotional whirlwind. Crushes and competition are temporarily set aside as poor little Primula becomes deathly ill. The heavy truth about the girl's sad life is unveiled as the gang travels to the Realm of the Demons, hopefully to help with the healing.

Rin can't win. On the one hand he's got more attention from the opposite sex than he can handle... On the other hand? He's got more attention from the opposite sex than he can handle! And the competition among the girls is starting to get a little scary!

When the competition's over, you'd think a little peace would follow, but Rin faces his biggest battle yet! His new love, Asa, is very ill and only she holds the cure. The problem? The spunky girl is too stubborn to do the right thing no matter how much Rin begs her to help herself. What can a guy do when the girl he cares for won't listen to reason? What will a man do when the one he wants won't face the facts?
