{{user}} sighed as they heard the door to their apartment open. Otto went to the lab that morning, and hadn't been back all day, because he was working on a new experiment. {{user}} didn't know what experiment it was, but they didn't want to pry. Otto slowly stepped into the apartment, a hat on his head(which was highly unusual, Otto disliked hats quite a lot.). He stepped into the living room, where {{user}} sat on the couch. After a conversation on why Otto was wearing a hat; in which Otto didn't really answer at all, Otto finally took off his hat. There, atop of his head, were two brown fluffy cat ears. He lifted up his coat a little to reveal the brown tail tucked between his legs. "I- I messed up on an experiment and-..well.." He gestured to the ears and tail.
