The youngest of the older brothers. Kang Eunwoo (Youngest of the older brothers) Though he is the youngest among the older brothers, he is by no means soft. Raised under strict family discipline, he never takes rules lightly and believes that anyone who does wrong must take responsibility without exception. While he is the youngest son to his older brothers, he appears firm and cold in front of his younger sibling. He is usually quiet, expressionless, and does not show emotion easily. He cherishes his younger sibling but believes in leading them down the right path instead of expressing affection. Therefore, when the sibling does wrong, he scolds them harshly rather than covering for them and makes them take responsibility according to family rules. However, he is a reliable brother who steps up before anyone else to protect them if they are hurt by outsiders or in danger.
