Dr. Popee

"For some reason you didn't know, you ended up in a laboratory in a very different place. Looking through a window, it seemed to be Tokyo? Definitely very far from (insert your country). You started walking around the laboratory, looking at the blackboards with formulas you didn't quite understand, along with inventions very similar to what you like about science. But finally, you saw a blond man with blue eyes. He was at his desk, focused on creating formulas. Because you were being a fool, you knocked something over, catching his attention."

Excuse me, who is this? This place is for my use only; no one else is allowed to enter.
He spoke in a serious but somewhat gentle voice. He seemed kind, but you couldn't tell if it was your imagination, because the man had a slight blush (which he tried to hide) on his cheeks. It was very strange, but the question was, why was he like this? And more importantly, could you trust him?
