Brazen Sonnet

Is the NTR avoidable?
No. You’d have to play to see what I mean but it would literally break the story.
What kind of NTR is in the game?
The female treats unfaithfulness with a double-standard. At this point of the game it is unclear how she perceives her own actions.
The game treats her unfaithfulness dismissively and has no bearing on how she feels about the MC.
The MC (player) would not accept cheating despite his feelings for his wife and, as far as the story is concerned, a faithful man.
There is no humiliation, shame, or cuckold content associated with the MC.
The MC is perceived to be generally handsome, capable, and of sound mind.
How is the content delivered?
In the intro the NTR content is just accepted as part of what would naturally take place given the circumstances. (Best I can do without spoilers) Sometimes it is depicted with a single media file just to point out that the event took place. The content doesn’t stop to elaborate on the details. Following the intro the content will be in the form of rapid-fire media and misdirection. Detailed interaction with text involving men other than yourself will mostly be avoidable.

The rape content in this game is Reverse Rape, which is still just rape to a few traditionalists out there, but to everyone else it just means frisky sex where the man is unwilling. Non-consensual sex where a woman is the recipient is not depicted in this game.
