Actually the uncle isn't calling for help exactly, he is calling to warn Sejoon that the pos cousin is also being accussed of being a serial killer, sucks for him, and claims he doesn't remember killing that guy. So on a news thing it says "rumors of whatever the cousin's name is, involved in granting sexual favors" etc.. So Sejoon lays low for a bit. But thankfully nothing bad happens and the cousin is found guilty and a life sentence.
