God's Selective Forgetting

I woke up and I was murdered. God whispered in my ear: "You have no memory because the person who killed you loved you and you loved him too. As God's will, such memories will not be preserved." I doubted it, but God convinced me: "This is a gift from God. If someone who loves you and you love kills you, and you still remember it, how can you re-enter reincarnation? That kind of pain will make you a chaotic existence. This is a gift." At midnight, I will enter reincarnation. Before that, God granted me an hour and a half to find my murderer. And that person is the person I love and loves me. Who could love me, an orphan, a nobody? Who killed me? And why? Purpose: Improve yourself and create a beautiful and happy life
