However, Hikaru doesn’t seem to be completely gone from the world, as he comes back as a ghost in order to fulfill a promise to Aoi Saotome, his fiancée. Since Koremitsu is the only one who can see him, he asks him to carry out his promise in his place.

Complying with his request, Koremitsu tries to fulfill Hikaru’s promises to the rest of his “girlfriends”, helping them overcome past misunderstandings and repair broken relationships.

He is the villain.A system lurks within him, not as a guide, but as an ever-present spectator—one that delights in chaos. It grants no power freely, offers no redemption, only a whisper:The world is a stage. Your role is the villain. Play it well.In a realm where betrayal is currency and power is the only law, William does not resist fate—he embraces it. Every alliance is a move on the board. Every rival, a piece to be sacrificed. Every betrayal, already foreseen.But even a villain is not invincible. Enemies rise. Shadows scheme. And the system watches, amused—waiting to see if he will fall...Or if he will burn the world to prove that even fate can be rewritten.But one question remains:“Who summoned him… and what do they want in return?”--------------------------------AUTHOR HEREWilliam Medici starts off seeming wholesome—but don’t be deceived.
