I mean... have you been keeping up on your weekly payments of ice cream to Pixie? She told me to tell you that it's a real nice ISP you have there... be a shame if something happened to it...
There's no branching storylines in CK (I am but one man! And also I don't like the whole "play through multiple times just for a few different scenes!" thing), but your "Kind" and "Cruel" choices are tracked and will in time open up certain events. Don't worry, though, some Kind/Cruel choices are repeatable and they don't counteract each other so you won't have to start over multiple times to see all the scenes :)
