I'm making changes to the game. Chase is the main protagonist. He was always supposed to be the MC but by saying four male protagonists I mistakenly made it seem like their viewpoints feature equally in terms of story time. The game will unfold through the viewpoints of the other characters as well but in a lessening degree of frequency depending on the character. For example, Wang's viewpoint features much more than Blaze's etc. Also, some female characters will also have a viewpoint, such as Stephanie.
The reason for having different points of view is as means to uncover the secrets, good and bad, of each character, which is the main theme of the game.
As for sex scenes, there will be many more in the next update. Best case is three weeks for the next update.
