What a boring ending

I actually wanted jun Jae to get his revenge each and everyone of them deserved what they got and more. Imagine raping and killing his sister who was just a kid as well. And all the torture all the kids had to go through because of this sociopaths and they still got to be saved. Well I loved this epeisode the must because it was filled with twist and turns and everyone’s secret was revealed but I am still sad ? for the ending because junjae was arrested. Maybe is because I am attracted to junjae, he embodied the role perfectly and that smile of his is heaven.
