"Right. Tell me about your plans!"
"Yes, but first, I'm curious," Eun Ha still had a question to ask. "Did Professor recover on his own, or did any external factors interfere? I mean ... Yesterday you were really bad. This is important."
"Do you remember being sick all your life?"

"WOW! This is too much! And what kills us?"
