We are newlyweds who have been married for a month. My wife Mayu is a wonderful woman who is cute, cheerful, and disproportionate to my dark, dark self. And today is Mayu's birthday. While on a business trip, I really wanted to celebrate Mayu, so I came home from my business trip with a cake in hand. Then, as a surprise, I secretly went home and waited... my wife came home with me. I couldn't help but hide under the bed, and then I had a shocking experience that made me depressed.
