Kiraware Yuusha wo Enjita Ore wa, Naze ka Last Boss ni Sukarete Issho ni Seikatsu Shitemasu!

The hero Ares was about to fight the final battle for the fate of the world. However, the three party members who became his friends on the trip said, "I can't follow you anymore!" Yes, he was hated by all the party members. Their patience had run out and they finally left Ares. But that is what Ares, the hero, wanted. The last opponent is the genie who is bringing destruction and chaos to the world. He cannot involve his party members in a fight from which they may not return alive. So it was his plan to play a disgusting person who would drive everyone away from him. Alone, the hero entered the final battle, and died… or did he? Eh? Am I alive? Why am I naked? And why is sleeping next to me? What happened? I can’t remember?! The hero who thought he was dead is loved by the girl who was the 'Last Boss' and living with her?!
