Finishing ep 6 juuuuust in time for ep 7.
Let's hope the MC won't leave any girls crying again in this episode but I have not high hopes. So far, I think, what he has done (in my playthrough) doesn't count as cheating. Sure, he slept with Alexis while fooling around but he has broken up with Nikki at the time and with Layla it's just flirting. Then the problems with Alexis kinda count as a break-up (although I didn't end her path) so getting back with Nikki and flirting with Layla doesn't count as cheating on Alexis. And then, the MC kinda breaks up with Nikki again as he heads back home.
Now, I doubt any of the aforementioned girls, that clearly have feelings for the MC, would like the 'competition' nor I think they will be very understanding if they find out that the MC was looking beyond. But still for such a game it counts as the MC being a saint.
