My theory is that, since FL’s family has the ability of prophecy - Maybe those prophecies comes in the form of kinda like a story book and thats why she thinks this is a novel shes read before? As for the other transmigraters, perhaps theyre just ppl who just so happened to remember from previous timelines? Since this is already the 14-15th time that the ML has reversed time, theres bound to be a few hiccups. But FL thought she was a transmigratier and when those ppl acted out differently from the “novel” she assumed they were transmigriters as well.
So ML is trash but he is that way because of FL. She literally made him into this mess. ML's family has an ability to regress, while FL's already dead noble family has an ability of prophercy. She got captured in her first timeline by CP and tortured immensly. Her family dead as they tried to falsify identities before. FL wants revenge against CP so she approaches ML for his ability. Except the trigger for the ability is a 'traumatic event'. So... FL literally traumatises the guy for like 14 timelines because he's just that kind of useful tool to her. In this current timeline ML erased her memory and send her to work as a maid. Basically it never works out when she rememberes being tortured by CP so this time she doesn't.
