I was made into the hero's bride.

"I have something I'd like to tell you," I was called out to the rooftop after school. When I passed through the door, it was a different world. I thought it was the usual otherworldly summoning, but something felt a bit different from what I expected. It turns out I wasn't summoned as a hero, but as the hero's bride. My partner is a classmate who was summoned as a hero beforehand—someone I know, but being told to suddenly get married without even dating seems troublesome. Even though I'm thinking that, for some reason the area around us fills with rivals emerging out of nowhere, leaving me and the hero behind. And the hero is seriously an angel. That's my otherworldly life. This is also being reposted on Alphapolis. I'd be happy if you find it even a little bit interesting while reading it.
