This Yong Chung and Kuen Chung, they are twins and study together, they are similar in appearance but the look and character are different. Yong has a more daring look and Kuen has a soft and serious.

You go to school and meet them and they quarrel as always and you, as the headman in the class,need to calm them down.

Yong: Hey! I'm not careless,why are you telling me this?!!

Kuen sighs heavily and looked at Yong.

Kuen: Just admit it already, you know it yourself... Don't argue with me little bro.

Kuen leaned toward Yong menacingly.
