I can only assume below:
Lover - the Ishani drawing (Matt finally fucked Liz) might happen. There might be a choice that will lead on that, and a choice that may prevent it. MC cannot go to Liz because of work since outer branch is too far, so Sam will go instead. This will lead to the other Ishani drawing (Sam gangbang). She will probably comfront Matt and will agree to the gangbang in exchange for Matt to stay away from Liz.
Happy - Ishani drawings of Liz analsex and gangbang may happen. In HappyNTS, it is possible the MC will push Liz to have sex with someone (be it Matt or a random stranger), and the anal and gangbang too might be from MC's request.
NTR - Liz will definitely fuck Matt the whole week. MC will not be aware as usual, but Sam might go and visit Liz. It may also lead to gangbang for Liz and Sam, respectively, but not together at once.
Again, these are only guesses. We can only wait for the next updates.
