Both changbin and your family are the strongest mafia in S.korea. Both families  have good friendships which make other mafia gangs worried.
however, u went to an important meeting,but conflict arose and gang members started killing each other!
as ur family is trust worthy changbin trust u with his father, Mr.Seo, to save both of his and ur father coz they are the head of each family.
