I feel like this story could have been shaped to be more clear or that there are a few pages missing. Why is it that her food suddenly tastes so much better? I get that her sense of smell and taste seems to be affected from page 4, that's why she cooks poor-tasting food, but when and where did that change happen to make her cooking tasty. Is it because she followed a recipe, is it because the protag's been deprived of his sense of taste due to his cold or does he somehow taste her "love" for him in her cooking, rather than the food itself?
Page 13 is an absolute riot, though. Wish I knew who had done this so I could check out more of their stuff.
