This was quite apparent in the 2nd arc where MC had a condition called narcolepsy where he tends to fall asleep randomly regardless of time and situation. The author used this detail to strengthen the spark between MC and ML, but then that's it. It was never mentioned again, not even hindering MC during the arc, and at the end the author just casually mentioned it. Also, what about the powers that MC supposedly have? That needs to be talked about, doesn't it?? At least you'd think there'd be an inner dialogue from MC, but no. It's gone gone.

MC quickly realizes something is off about his system. In return for him being pissed and distrustful, the system treats him coldly and doesn't explain what he needs for the next mission and just lets him go in with no information. First time I've seen such an a**hole system in one of these stories. Later the other players confirm his system was abnormal; none of them have their memories wipe every time they come out of a copy, he never received a basic players handbook, and he doesn't even know his systems ID number.

in copy 3, in one chapter he summoned a devil and the next he was a cat, then he's talking to a mermaid duchess, then he suddenly got eaten?? Huh? There was no transition or flow from one scene or chapter to the next so I think the pages of a totally different story got mixed in for some reason. It jumped around and made zero sense. Even less than usual with mtl. Hopefully this translators copy doesn't suffer from the same problem.

that the MC is not a normal player appears in the first arc with the revelation that his cong**ital illness is actually a side effect of his special ability. ML is revealed as monitor K by the end of the first arc. They fall in love way too fast, but there is probably something more we don't know behind this.

The first player from the first arc (fake boyfriend) is revealed to actually be monitor J. The MC is suddenly the incarnation of a mirror with no memory beyond the past month or so. He views J as a trustworthy brother. The MC choose the code letter Q during his flashbacks in the mirror maze arc, implying he might now be a monitor. This is either a flashback or the MC is being HEAVILY gaslighted by J. I think the latter is what the author is aiming for, but it doesn't make much sense with that players casual or even incompetent attitude in the first arc. I also suspect the voice he was hearing through the third arc might actually be J rather than K, but that would mean some serious timeline hijinks. I think J was in the mirror maze arc as well as one of the other player's summons. It's currently established that at least two monitors are being sent to investigate the high death toll of various worlds. It may be a setting that monitors must enter the worlds with their memories suppressed, or something done to specifically restrict and harm Q/K. If it's to all monitors, it could explain why J was so low key in first world. But does that mean MC was always a monitor and his memories in the hospital are either false or distant history? So is J just doing his duty or is he manipulating Q/K? WTF is happening with the timeline???

I am hoping the fourth arc is the returning memories and we aren't actually out of the mirror maze yet. It would be terrible story telling, but at least it would make sense.

The entrance to the game was a fountain with a Guide/Commander in charge of explaining details. Some players have special roles and start with summons. They are also meant to help grant monsters to normal players. The MC gets his summon, the ML, and starts heading to the next checkpoint with the guide. Okay, good start right? This is where it starts to get weird.

The author attempts to bring the survival horror aspect back in by making each checkpoint (???) a different mini scenario the players need to clear alone with their summons, or so I surmised after the MC was transported into a high school mystery setting as a cat. Literally. I'm not really clear about how it works because we never get to see the guide again or another checkpoint. The setting just suddenly changes to some kind of multiplayer fantasy town. Sometime in that gap, something goes wrong with the MC's summon. He needs to make a proper contract with the ML to move on to the next stage or to further explore the maze. If I had to guess, the ML made the MC upset enough to give up on his summon or they were separated by the rules/by meddling of that one lady who drew the snake summon. What is certain is that MC needs to draw a summon at the fountain and he must earn currency to do it. He takes on the quest of the mermaid 'duchess' and accompanies 'her' to find her stolen necklace. It's revealed to have been stolen by a mermaid duke and hidden in the room he uses to stash his treasures and his hybrid tree person son. This is all revealed by the 'duchess' who turns out to be the ML in disguise. He fades away once the truth is revealed and the MC takes the necklace to the real duchess.

MC and ML reunite and talk about the secrets of the maze. Turns out it's impossible to clear??? ML is about to restore the MCs memories when a shadow appears and swallows the MC alive. END OF ARC

he is K or something

Like, MC's name most of the time is mentioned as Shannan as compared to his translated name "Xia Nuo". Not sure of the Ml's name used in the second arc, since it's currently being translated, but his name in arc 2 is Canland/Canlan. The other character's name is pretty mismatched too. So, it's a bit difficult to understand, I guess.

Reading "Thriller Trainee" had actually up-ed my expectations for horror quick-transmigration /infinite flow BL. Though a bit disappointed but at least enjoyed the first arc. Hopefully the later translations will make more sense. I'll comment on this after at least a quarter and a half of the work gets translated, so that there's more room for comparison. Maybe by then, the story would come together to some extent.
