"The more taste it has the better it is." Xue Yang isn't afraid of the spice but he will accept that she wants to blame it on the food and not her own sentiments. He doesn't hold any of the same kind of feelings or nostalgia that she has.

Xue Yang worked alone. He never was part of any sort of military or work well with others. When someone wanted something done, he was enough to take care of it. Which meant he had no such connections to other people.
