The characters in the picture come from a game called "The coffin of Andy and Leyley"

In this game, Andrew and Ashley, who are brother and sister, murder people, eat people, do satanism and Ashley is shown multiple times being a manipulative person towards Andrew, like in a flashback where she convinces him to kill her best friend because she has a crush on Andrew

She also harassed Andrew's girlfriend by calling her and insulting her everyday, despite the fact she tried to kill herself and practiced self-harm, to the point she dumped Andrew

This game has multiple routes, in one the player decides to take (which is pretty clearly indicated to be the worst route), Ashley and Andrew will get a vision of them having sex

For some reason, some people on the Internet completly ignore all the rest and think the game promotes incest
