So far the remembering past life has no meaning to the story
Ikr ╮( ̄▽ ̄)╭ the only significant thing it had was that she knew how to use cutlery. And maybe that she is more polite and smart (since she probably had no education what so ever in this life we could says she is like that because of her past life). but it is all small details, literary the only things we could maybe says was because she is reincarnated but it had no real meaning to the story since it is so miner and all of it could easily be written off as her personality/potential or that her mother taught her ╮( ̄▽ ̄)╭ but I still love the story nevertheless (▰˘◡˘▰)
It sounds interesting but I feel the first ch is missing some info. Hope it gets cleared up in the next few chs
