Ok... They created 9 more. Started with 3, so 12 then? Hidden one. So total 13 issues running about.
And.... I was starting to think each kiss generates 3 more each time, as that seems to have happened all the time. And I was also going to assume each girl can only generate when they kiss a dude for the first time... But if they only created 9 more the math doesn't add up....
There are some things to be figured out on that angle.
