After clashing swords with the Demon King countless times, following a long struggle, he finally struck the Demon King down. The world erupted in joy, and the people hailed the Hero as a 'savior'.
But from that day forward, Lucian became a different person. He opened his heart to no one, never smiled, and ceased to interact with others more than necessary.
