If Santi really is Gabis husband (which i hope), that's the cherry on top of the cake
Just imagine the scene, a angry Santi storms in Emilys house and shouts for their shitstain of a son, which is fucking his wife and knocked her up.
Emily which is completely devastated that her son could something like this, doesn't care at all for his bio dad and that their will never be a happy ending for Emily/Santi/MC.
MC which just comments, if u want to see how to satisfy ur wife, i have it here in 8k.
It would be glorious
