From a dropout to a training facility instructor?

A reincarnated protagonist who obtained a rather inconvenient ability transforms from a dropout after graduation and, for some reason, gets caught up in various things—becoming an instructor at a training facility behind the guild, a lecturer at some magic school, a researcher at a laboratory in the royal capital, and more. "It's all a misunderstanding! I'm not that strong or amazing!! If I work any more than this, I'll die from overwork!!" (※inner voice)
