You guys can use
Universal Renpy Mod to find the variable effects of choices on most games.
Some discussion of the routes with spoilers ahead.
Basically, there is np, wp, and individual girl points. np is the cuck points. wp is the "manly" points. In general, you get wp by training with fleshlight and standing up for yourself. You get np by being a cuck obviously.
Now there are a few crucial choices. First is choosing to subscribe to Giani's webpage. Subscribing is major cuck move and even if you got every wp up to this point, this choice will lock you into the cuck route. Mia goes on the trip and the MC is really accepting his cuck status on this route.
Next crucial choice is at the club. If you didn't subscribe to Giani and made some non-cuck choices along the way, you should be able to buy the whole bottle and prevent Mia from going on the trip. If you have high Riley points, she will also stay behind. That's maybe chance for a long shot harem route, but I guess it might also backfire if you cheat on Mia. You kinda lose the high ground when confronting her next update. That is, if players even want to have her back. Dominating a cheating cunt is pretty cool in my books. Use that guilt, my boy! Let's see how it plays out next update. Anyways, this route ends with you finding evidence of her cheating when cleaning her room. You still have the choice to enter cuckroute if you jerk off here. Otherwise, it's "to be continued" where you will confront her and hopefully tear her a new one. What a cunt lol.
If you didn't buy the whole bottle at the club, you have the choice to masturbate like a cuck to Mia's cheating during her trip or to break your monitor in anger. Again, if you did not get >10 wp, you automatically jerk off and go into cuckroute. Cuckroute and non cuck variation of this route ends at the same place. Before you are about to confront Mia.
In case it's not obvious, this game is called Girlfriend Tapes and was obviously NTR from the start. Not even sure what vanilla kids are doing here. I mean, it played around with the mystery aspect for quite a while, but only the most deluded people would have thought a story set up in this way would be anything other than what we got. As for the "non-cuck" route, it's still pretty NTR, but the narrative focus on the MC makes it a bit different. Anger instead of despair is the key difference between a helpless cuck and a normal dude who got cheated on. The Mia points and Riley points must mean something. We already see Riley having genuine feelings for the MC. It is likely there will be some bittersweet outcome to this by the end, at least on some routes. The cuckroute MC is already fully on board the netorase, so he is happy as a despicable cuck I guess lol.
I don't think there is quite the true NTR route where the MC is not a willing cuck, but still too weak to do anything about it. Will have to see how it plays out at the end I guess.
