I would actually like to know this too. I should think it will entirely depend on what K7 does with 0.23. We will either see the wedding for all of them at the same time, or we will see individual weddings for each of the girls to the mc. I am hoping its just going to be a mass wedding, with all the girls repeating what is said, and the same for the mc, and then they are married, he puts the rings on each of the girls. I think individual marriages is just a lot of effort when it can be accomplished in one go with them all on the beach at the same time.
0.24 will be that we see them near the end of their pregnancies ( women don't produce breast milk until around 6.5 months into the pregnancy, and the breasts certainly don't just pop out inside 6 weeks as is the case with sandy lol) this is what is being referred to as the time skip. I think this time skip will likely be used several times to close the story. I personally think that when we see the daughters reach 18, the game / story will have come full circle and I think the game will end. I don't think we will the mc banging his daughters before they reach the end of the game, i mean i could be entirely wrong, but to me it just sadly seems fitting to end the game once your daughters have turned 18. The real purpose is so that K7 can finish up this game and give their full attention to MNM. We might even be surprised by the way 0.24/ MNF 2 will go, in terms of how the the time skipping might go.
