The main protagonist is Max, and the primary female character is Mei. The entire game is presented from Max's perspective, but in certain scenarios, players have the option to view events from Mei's (or other female characters) point of view, providing a sense of mystery.
All scenes are optional in the sense that players must make specific decisions to access them. However, after reaching a certain point in the game, the "route" is locked, with events unfolding one after another, albeit with more freedom in certain aspects compared to the previous game.
There are three main routes to choose from: NTR Route, Love Route, and Corruption Route (this route has an optional netorase mini-route). Additionally, each of these routes offers various alternatives based on another system.
Edit: I have been playing with the idea of a special mode where you take control of the girls and do events with them but idk yet.
