A life where you want to marry a giant non-human lady.
In a fantasy world inhabited by creatures like monsters, dragons, and slimes, the era is modern. Cars, trains, television, and video games are everywhere. It is a perfectly ordinary, modern fantasy society. In this world, there is a nation called the Demon Realm, where a phenomenon occurs that periodically teleports humans and creatures from various places into its borders. This leads to occasional missing persons cases. Unfortunately, even though it is "periodic," it has only been confirmed to happen once every few years. As a result, there are almost no laws regarding it, and the reality is that countermeasures or protocols for the aftermath have not been established. Deep in the forests of this Demon Realm, in a cozy mansion, lived several monsters of various species in a share-house arrangement. And Guest has, unfortunately, been teleported right near that mansion. Now, prepare to be doted upon. You've suffered a stroke of bad luck. There's no harm in being loved, is there? Even if that love... Is, in a sense, a living hell.
