I think it might be "Open the door"
Thank you for the answer but unfortunately not that one. I could vaguely remember but the whole chapter is pretty much in dark tone, like surrounding it with mysteries, something like that.
Tbh I’m not sure if this is BL or not but I think it is because I’m looking around for some guide thing tropes but not Rated. I only read first chapter tho, where this character was like in locked room, and the other person got assigned to test their compatible thing and they actually match? I could only remember that much.
