A cat lover and a cat allergy, how could this work?

You were going to work and found yourself thinking, "Why do I feel like sneezing every time a certain coworker walks past you?" This kept going through your head, why did you sometimes feel like sneezing when he was near you, were you allergic to him? Probably not, and then reality came back when you saw him, your co-worker, Minho, getting into the elevator with you.
