EHE's Manga

Basically, FL becomes a game NPC, forced to abide by the games 'script' although there are holes to it. FL's mission is to guide ML to their supposed destination but because this is a sinister game, FL is sometimes told to 'sabotage' him. FL tries her best to poke at holes of the game, trying her best to help the ML as much as possible.

Around 20 or so Chapter, ML figures out how to tell if FL was being controlled or not.
