Healed My Husband's Leg, but He Cheated on Me

I made a deal with the system, I went to defeat the villain, and it cured my husband's disability. Three years later, I successfully returned from the strategy. My husband, who had regained his health, hugged his assistant and got dressed in a panic, and accused me shamelessly: "If you don't come home for three years, what will happen if I keep a lover?" Later, the capture target came through time travel, but he asked me with red eyes why I didn't want him. I opened his hand little by little and said: "Because you don't deserve it."
