well if there are a reason surprise me in future updates, but in my opinion the last scene is great chance, mary can have regrets after and reject because is only one time thing but then you can open other routes like jelousy, hidden ntr, ntr ,corruption, netorase , uncle harem and start to change dialog and make conparations etc if mary and kendo dont have sex it can be difficult add other things more than the foreplay and you cant add jelousy becase mary and kendo dont have a deeper conection is only for fun, she have satoshi and more dificult when mary reject kendo becase she love satoshi, ntr is more change felings than have sex for fun,and i talk when i dont know youre plans and is based to what i played but i like youre game and would like to see more, I'll definitely buy it when comes out
