"I never thought studying can help with cleaning toilets and areas. Studying is never useful, to begin with! I have never, ever seen humanities being used in real life. Unless you're a historian, a newspaper writer, or a report writer. You'll never see it being applied in the future." Rein mumbled to herself.

"It's so weird to see that quote being used around the world. I, Rein, will say that studying is bull!"

After Rein complained about a problem that she thinks she needs to discuss with herself, she decided to set foot into the outside world to go to school.
