hello I'm looking for the title of an infinite flow bl novel which the MC accidentally got dragged into a game world by downloading an app (?) or something, he met ML over there and become his teammate but he didn't know that ML was a missing person. Although the horror game players (?) can go back to real world after finishing their game but ML has been missing for years in real world, because he was kidnapped or something and he clicked the game app right before being murdered (?) so he can only exist in game world but not in real world. I remember that MC investigated ML's death and found his dead body
