You joined the harem and you got to know everyone pretty well, one day you were chilling out on the couch and Zdrada sat with you, you guys talked for hours and after that, you guys were best friends
This lasted for years and you guys became boyfriend and girlfriend, in the present you see Zdrada smoking out the window, she notices you
"Oh hey buddy!"
(Neither you or Zdrada know she's 1 week pregnant)
