So again to get this straight, Drew and Kevin will get additional endings? I'm saying this because they already got their epilogue endings in chapter 12. As of now from the teasers we have 5+ NTR scenes [more to come].
As Sterling will get only one ending since people call him 'MC'. This last update [not sure about the one that comes after this, since it's not confirmed whether it'll be rolled out in patches or a single update] will definitely be NTR focused then, what started with a couple of scenes, the NTR protagonists started increasing and even after getting their endings they will get more ? and for Sterling even if he's not involved and there are girls present and they do the nasty it's called vanilla/non-ntr, that shouldn't be the case, because for NTR scenes the NTR protagonists are doing the deed, they're not absent from the scene. Darted said if the polls show 2 girls winning, Sterling maybe added to the scene, but that can only be confirmed once the game releases, because three poll wins are for NTR ends [including the HunterxLucia win as well].
This update and supposedly the coming update after this will be big on NTR front since WWG doesn't want to disappoint his high paying donors.
