Have to disagree with you here if what you are implying is true then in would be Incest and patreon will ban it .
More logical explanation will be that john has something to do with MCs aunt that caused her illness .
Hmmm, yeah that might be true. It's just with these games, it is usually something related to sex and finding your parent is someone else or something like that.
But, now that I think about how nicely Orb has been writing the story, I doubt he will use tactics like naming John his biological/real landlord or something to avoid getting banned. So yeah, probably your explanation is better. But then I am sure John must have used his Aunt for his sex racket somehow ;P.
And even the theory that John might be proposing something to his parents in exchange of sex like money for the medical bills is very plausible as well. In that case I will like the option to break john's face badly. How dare he go after MC's Mom. I just hope no forced ntr. It is already sad to see Sylvia not being enjoyed by MC XD.
P.S.- Let's see what one of the best games has in store for us. But man, waiting months for an update is so cruel when we find such amazing games. I hope this game has still a long story ahead, and hopefully a good closure. Also, this is the first time for me that I am readily open to not being given a Harem ending choice. I will just be satisfied with MC making Nicole his forever.
P.P.S- Nicole's renders and scenes are THE BEST.
