From you comment, I thought that you were for Netorare, but then I saw your profile… So I understand that you’re in fact not.

Anyway, games and reality are two distinct things. In real life things happen and we just have to take decisions accordingly to them, in games, fetish are included for those that are into them and an option can be present to prevent them from happening for those that are not into them.

Then again, there is – at least – two ways to implement such an option :

1. Just making it so we don’t see the concerned scenes (this is generally considered the worse one – for good reasons)
2. Making a second branch in which the concerned characters never interact – or even never seek to interact – in such way.

Note: I don’t know which one it is in this game as I didn’t try it yet.
