After his death, a young man accepts a mission from the System and strives to conquer a continent in another world.
To his surprise, before the mission even begins, a mistake changes his gender, turning him into a girl.
Things take an even sharper turn for the worse: not only does the Hero, who was supposed to be killed, turn evil, but she also makes him her lover.
Fortunately, when it looks like completing the mission is hopeless, the System takes pity on him and replaces his main quest.
[Ding! Host, grab the Hero's leg and beg her to conquer the continent.]
"Ah! Are you serious?"
The Hero: "Big Sister Teresa, you'll always be mine. This time, I won't let you escape."
