A practice match was a normal thing to do for a Martial House. Usually, a martial house would propose a practice match to another martial house at the same level.
This happened when the competition was approaching. The practice match served as a warm-up for the members of the martial house.
As the Fighting Anteriority was getting near, Kang Dong-Woo urged his sister to seek an opponent for a practice match. The boy wanted to test his progress in the last month.
At first, Kang Seo-Yeon was not that enthusiastic about the practice match. But then, she remembered the story of how the two sisters got to know with Heero.
The head of Iron Fist Martial House, Yan Tie fancied Han Ying. This guy used black means to get Han Ying, but Heero saved her.
Iron Fist Martial House sent their men to take care of Heero for interfering with their deed, but Heero took care of these people. There was no continuation afterward.
