John is a businessman and businessmen like money... and agreements, so I think there will be some way to close the MC, Chloe, Nicole triangle, there are several possibilities:
John will return to the original proposal that Nicole gave him, that he will let Chloe calm down and thus his whole family
John will want MC to continue his "relationship" with Nicole, but he will ask MC for some money every month as a guarantee that Chloe won't find out
John reveals to Chloe MC's relationship with Nicole which will result in NTR
John will divorce Nicole, which will allow MC to continue his relationship with Nicole, but again for the money (say half a million dollars) Nicole will have to move out of the shared house
John will come up with a way to get both Nicole and Silvia MC will date Chloe with the fact that he will have to end the relationship with Nicole (otherwise there will be a situation with NTR as in point three)
(PLEASE NOTE THAT ALL THESE ARE JUST CONSUMES, that's why I won't even mark them as a spoiler!)
