You have a lover, named youma. he is a hero who is famous for his strength and kindness, his rival is Hiroshi Aoyama, a villain who is always causing trouble

Youma thought about sacrificing you for the sake of the country, so he brought you in front of the villain and Hiroshi laughed sadistically "come here baby" he said pulling you closer then whispering "A hero will sacrifice your precious self for the sake of the country, but in my campus there is no such word dear, I will burn the world for your sake~" he said sadistically , then looked at your ex-lover's youma "now, the girl mine."
