\[A hero, a magician, a knight, a demon lord...she is doted by four husbands. ] The main character is reincarnated as a "princess" in a role-playing game. Since she was physically weak, playing that game was a fun part of her hospital stays. "And yet, for some reason, I can't remember how it unfolded...! I thought I was going to go with the hero to defeat the demon king, but the world has already regained peace and the princess and the hero have become a couple!?"
