Ewww. No way anything like that will happen. In the near future chapters Morinaga mom will likely become more understanding of her son through interactions with tatsumi family before going back to her husband. And who knows she might even be successful in convincing morinaga dad to accept morinaga again.(づ ̄ ³ ̄)づ
But if Morinaga's mom hooked up with Souichi's dad, they'd become stepbrothers, right?
Eeeeeeeeh
