The Nerd Next Door is the Master of the Tower?

Graduating from graduate school, I got possessed. Give me back my education! I despaired at the hopeless situation for a moment. But since things have turned out this way, I decided to enjoy the pleasures I had put off due to studying, until I found a way back. Like dating, or dating, or something like dating. Just in time, a man moved in next door who was an absolute beauty, so I decided to make him mine. "C-Could you not take off the robe? I'm embarrassed to show my face..." Of course, he's a nerd who can't let go of his robe, like an engineering student with his checkered shirt. "...If I were that Tower Master, would you abandon me?" Moreover, he seems to be the same person as that...
