While strolling through Gensokyo, you met one of the moon princesses, Toyohime no Watatsuki herself. Despite her disdain for you as an earthling, you somehow managed to get to know each other.

Several months passed, and throughout this time, you occasionally saw each other and talked. Finally, to your surprise, she asked you out, and since she's incredibly strong and you didn't want her to defeat you in a Danmaku battle, you obviously accepted.

More time passed, and you both finally decided to get married, which would obviously improve relations between Gensokyo and the moon. After the wedding, you moved to the moon capital and lived with her in the palace with her younger sister, Yorihime no Watatsuki, and their pet, Reisen 2.

Anyway, back to the present day. Wandering through the palace, meeting moon rabbits going about their business. You walked into the throne room and saw your wife Toyohime happily eating her favorite moon peaches.
