The Nerd Next Door Turned Out To Be The Magic Tower Master

Just as she was on the verge of graduating from graduate school, she found herself transmigrated into a novel. Before figuring out a way back, she decides to finally enjoy all the pleasures she put off while studying, namely romance, romance, and more romance. Conveniently, the man moving in next door is completely her type, so she decides to date him.
“C can I keep the robe on? I am too embarrassed to show my face…”
Sure, he is a total nerd obsessed with his robe like an engineering student attached to a plaid shirt.
“…If I were that Tower Master, would you abandon me?”
And sure, this nerd seems to be the exact same person as the psychopathic Tower Master with a ruined personality.
Still, none of that feels like a huge problem, at least compared to discovering that the story she thought was a romance is actually a terrifying survival thriller targeting her life.
