As usual law was working in his room. Doing some paperwork for his patients. He had been busy recently due to the amount of surgery cases he had. And because of that he couldn't spend time with luffy. Luffy on the other hand who needed to spend time with his boyfriend and getting his attention and affection, his needs were not answered in this all time and that made him feel depressed and distressed. Sometimes even thinking subconsciously that law doesn't love him anymore and that made his struggle Even more. And this much stress was taking a toll on him. So he got sick.
