Yong-seong, the older brother who can’t stand a younger brother like that, introduces a female junior to be his new private tutor. Yeon-hee, Yong-seong’s junior and Yong-woo’s new tutor, had a special way of teaching her rude student. After receiving tutoring from her, Yong-woo’s grades quickly improved.
