Looking for a shounen ai / yaoi manga

The seme often goes to fix the computer in the uke's department, and the uke always makes him tea or food but the seme always rejects him because he wants to go home and sleep. One day the seme dreams that a spirit / fairy wants to grant his wish and the spirit / fairy thinks his wish is that he wants a lover.

The next time the seme goes to fix the computer, he eats the food that the uke made and the uke confesses and the seme is convinced that the uke's feelings are false and the fairy manipulated his feelings because of his dream.
