Hero, I Didn’t Take Your Saintess Away!

The hero is called from another world to this continent and, after much hardship, succeeds in defeating the Demon King. Among the heroes who defeated the Demon King together, he develops feelings for a beautiful saintess and prepares to confess to her. However, while he is away from work as a hero... an extra who rolls in from somewhere bares his poisonous fangs at the saintess... No... This is a cruel story that tramples on those who are mistaken, and a story of paying a harsh price for a romance that was created on one's own.
