Gintoki the Butler and the Tsundere Hero

The Odd Jobs Agency receives a new commission: care for the beautiful single woman living across the street, for an annual salary of one billion. The masked man in charge of hiring tells him that the woman is wonderful in every way, except that her illness has made her a little bad-tempered. She uses a wheelchair, has lost her memory, is incredibly rich, and is so beautiful that she is exactly his type. She is tsundere and bad at being honest. But she is super cute when she gets angry, too. And, incredibly, her surname is also Sakata, the same as his. Under Gintoki's attentive care, the woman grows more and more dependent on him. But one day... [Tree-Sea Transformation Alert] It lasted only an instant, yet he felt as though an eternity had passed. After that strange sensation, Sakata Gintoki heard the pink-haired woman look at him with a bewildered expression and ask: "...Who are you?" Was this what that person had called her illness? Sakata Gintoki lifted her out of her wheelchair. "Do you remember who you are?" The woman shook her head. "Then let me tell you." Her bewildered face was reflected in his red eyes. "You are Sakata Rika, and I am your husband, Sakata Gintoki." P.S. The heroine's physical disabilities will become increasingly severe as the story progresses, but in the end she will make a full recovery. Happy ending.
