Why Seo Jang-hoon gets angry when people say he looks like Chae Chi-soo

Our national team used to easily crush even the Japanese youth national team.
And you're comparing him to a player who wasn't even a national representative and barely made it to national tournaments?
Seo Jang-hoon had the skill to toy with Sannoh, who are portrayed as invincible in the manga.
Especially since Hyun Joo-yeop was in the lower grade,
during his senior year of high school, they won 9 out of 11 national tournaments and were runners-up in 2.
The Korean high school national team back then was truly incredible.
