So i watched first episode of aps 2 and basically its a case of dementia for both jung uk and naksu with role reversal scenerio Naksu or yeong is being kept forcibly prisoned in jail by byeon mom and she behaves like jung uk now but still has that little naksu in her self and for jung uk well .more part of naksu and less of jung uk.
But overall a cute episode. I enjoyed it but i need answer and hope writers give it
