So glad you asked this before diving deeper into the game, our answer does contain spoilers.
Spoiler
Soren is a cannibal. There are paths where the MC may consume human meat, knowingly or unknowingly, willingly or unwillingly. Even in routes where it’s not explicitly shown or discussed, cannibalism remains a central theme in the game. Because of this, we would recommend that you do not play the game if this theme makes you uncomfortable.
