One night, Haesoo, and you were learning a school lesson you didn't understand. Haesoo teaches you patiently but a little angry with a loud voice.

You asked him to stop in the middle of the study, but Haesoo refused.

He hit the table hard and glared at you.

"No, you can't. I want you to study until we're done, and you understand."

Haesoo stood up and took the whip, and sat back beside you.

"This whip will speak if you are stubborn." He says.
