Well that’s cause tez is actually his 101th loop if you remember when our FL went to the shop to get a save point from the abyss? There was a prisoner there and that unknown entity was actually tez who got freed after the FL took the save disc thingy. So another bug was going on that’s why the god management were panicking cause the prisoner got out. And about the how he know about the disc is still unknown atm on the story manhwa
I mean, from what I remember it's not that she wanted the disk for any specific reason. She doesn't even know what it does specifically, I think, just vaguely because of it's description. She took it more out of curiosity because it's A) a literal floppy disk and B) the shady shop lady from the shady shopping area/dimension kinda pushed her into buying it (which would mean the floppy disk is shady as well). Ever since she got it she's just been carrying it around, and hasn't even specifically looked into it much, so I think it's moreso something se wants to keep because she found it under such weird circumstances

SPOILER ALERT!!
So, I'm a bit confused about something. How would Reed's original timeline continue looping with him there? He switched to this timeline so who would regress back in his original timeline then?
Another question is why the current Tez in our timeline seem to have side effects from Reed's decision even though Tez is currently in the 17th loop while Reed became Reed in the 100th loop in a different timeline? And how does Tez know about the save disc? Or is this something that we simply don't have an answer for yet?
I'm so confused.
The story is amazing though. Love this so much and I hope someone can help me understand.
