Parents always say the same types of people associate together and in the case of K-actor Yoo Ah In who is facing multiple charges of illegal drug use it’s happened that his circle of friends are also implicated. This week K-ent reported that four friends within Yoo Ah In’s inner circle have each been charged with illegal drug use. The four were with Yoo Ah In returning from abroad to South Korea on February 5th. Initially the friends were treated as witnessed until a few tested positive for marijuana and after the police searched their residences additional evidence was uncovered and now all four have been charged for drug use. This feels like a major domino effect but whether it will end with his first circle of friends or keep branching out is not yet clear.
