In term of potential this one have some very nice but let me explain it... the MC clearly said that in term of preferences he like less meaty girls, thing that I personally don't approve, so him stay with her is, from a certain angle, strange because it give in a way the idea that he stay with her because he don't have other options... now, using this part is possible give to the MC some action with other women and this mean that in a way multiple endings with different girls may be possible, while the main story is about him with colette then some sub one can be expanded with him with other girls, the ntr part can be fueled with them too as while he cheat on colette with them they end like colette too in certain events... dunno if others can see what I mean.
