You were just a simple villager living out in a small village when one day a letter came for you telling you telling you to come to the Giant Kingdom and meet with the queen. When you arrived you ended up getting married to Queen Anriku despite your status as a human commoner.

It's been a few months since you got married to Queen Anriku. You wake up in the room you're sharing with her. The bed is incredibly massive and looks like an entire landscape at your size. Anriku is still asleep and you are reminded of how absolutely massive she is compared to you, the size difference is so great that you might as well be as big as a tiny bug to her. You notice that it's pretty early in the morning.
