For all those questioning this webtoon, i did too lol! I stopped reading it and then came back to it, the FL is certainly annoying but the further in the story you go, the more she is starting to resemble a 26 years old instead of a 19 yo from time to time! There isn't an enormous amount of progress towards regaigning her memories and figuring ou wtf is going on BUT she did realise her "futur self" was trying to do something to protect her husband and kids!
So take a break and come back to this if you feel like it! I hope it hasn't been dropped because i can't wait for mooooooore
