By the way, people who are going to play it, the third picture is of another man having sex with the MC's mother and they show it to you, and that's not the only scene, there are 3 more, really pathetic...
To clarify for anyone reading: the mother/stepmother is a side character, not a main romantic interest. Seeing a secondary character with her own partner is not NTR, NTS, or cuckolding, because she is not the MC's partner to begin with. The game focuses on the actual main characters, like Mia. There is no cuck content here.
