Baekhyun screws up, Sehun and Jongdae don't care, Minseok laughs and Luhan has to fix the mess.

Firstly, we have Mr Byun, the cause of all conflicts, the little troublemaker with a mentality of a little child. Next, we have Mr Lu, the peacemaker, the patient one, the guy who just loves his little Byun. Thirdly, we have Ms Kim, Byun's uncanny obsession, often the cause of Byun's antics. Fourthly, we have Mr Kim who has absolutely no relation to Ms Kim other than perhaps acquaintances and occasional workmates, the guy on the sidelines whose main objective in everything is laughing. Lastly, we have another Mr Kim, no relation to the previous two Kims, and Mr Oh, the two stony-faced guys who are just so over everything.
