The Yandere Hero's Thousand-Layered Schemes [Reborn]

Lydia died a glorious death in the final battle against the Demon King. Fortunately, Heaven took pity on her and gave her another chance at life. She decided to grow stronger and do her best to survive to the end, so she could save the world.

After being reborn, Lydia discovered that many things had changed from the way they were before. She found the future hero early, just before her own maid nearly mistook him for a male incubus. She planned to shower him with equipment and magical knowledge to make him stronger. But why was the hero, who spent every day by her side, starting to act strangely? He was getting more and more manipulative by the day, and all sorts of bizarre dreams kept entering his mind.

Could she please just be allowed to save the world in peace?

Probably a tragic, scheming, lovesick, slightly manipulative male lead and a cheerful, goofy female lead. Happy ending.
