I'm Overworked, Reincarnated and Now Desperately Trying to Live With the Help of a Stony-faced Magician and His Magic Fingers

Story :  "I've been feeling strange ever since you arrived here. I'm terrified of being alone again." I was taken by the way he looked at me. He was supposed to be the cold and distant magician, and I was supposed to go back to my own world, but now I don't think I could ever leave his fervor behind... Overworked office worker, Yuno, found herself being reincarnated after she was involved in an unfortunate accident. Before she was sent to another world, God told her that if she stopped an assassination plot against a prince in this new world, she would be sent back to her original one. Now, as a maid in the prince's castle, she tries to approach His Highness, but instead catches the eye of his cold and merciless magician! Thinking she's suspicious, he immediately starts to investigate her, including every inch of her body! Then, after he reaches her most intimate spot, the stony-faced magician suddenly shows Yuno another, very unexpected, side of him!
