Most lactose intolerant isn't fatal. The sex, especially when the MC is pregnant (like the doctor said, the pregnancy is VERY risky), could results to higher harm. This is not like the most lactose intolerant having stomach ache and diarrhea with cheese, this is a body with death potential. Well, enjoy while it lasts. It's fictional anyways, LOL.
So both of them do realize MC has a weak body, right? A sensitive with higher sickness potential. And the 24/7 sex they did while considering the MC has a weak body, right? The somnophilia?? The sex right after MC gotten better from fever?? The sex, sex, sex— They did it with MC's weak body in mind, right...
(No, it's not right. It just a satire since I know they didn't)
