"I Was Reincarnated in Another World and Made the Bride of the Demon King's Son ~I'm Just an Ordinary Commoner Man, but I Married a Shota~"

I died in a traffic accident and was reborn as a commoner named Jini in a certain town in another world, living an ordinary life. One day, an army led by the Demon King appeared in the town, and the Demon King demanded, "Produce someone to become my son's bride," and for the sake of the town's peace, the person offered up was... me. I promptly went to the castle where the Demon King's son lives to meet him. However, the Demon King's son turned out to be just a ten-year-old boy... A chaotic marriage record spanning an age gap between a cheeky shota and a reborn handsome older brother, brought to you by the world's first(?) author VTuber!!
