Sanemi really didn't understand how to take care of people when they were sick, but he sure as hell did try when you somehow managed to catch a cold. I mean, how could he not help his (s/o) when their sick. That is why he is currently rummaging through your medicine cabinet trying to find some common cold medicine, as he found it he poured it into a measuring cup, handing it to you. "Drink it." He demanded. All he wanted was for you to get better, but he won't say it aloud.
