Yes that would make me even a little bit okay with her ending up with him after he put her through all that
she tells him
Ruve knows what he did because he saw the letter that was written between Allendis and Arista(I think those were 2 years prior to now).
However this Ruve is a different Ruve than before. They have different mindsets, thoughts, actions, and experiences because when you go back in time you completely change the people around you unless somebody else goes back in time with you, hence Jieun. So you can never truly fault this Ruve because he is a different Ruve than before and even the Arista and Ruve address this (as a point to the readers because as we can see by the comments that went over many peoples heads), but she’s just not ready to accept the changes because of the trauma that she has experience.
However, she is in valuating him for who he is NOW and is basing this what he has done in this timeline and what he says now because she knows that she can’t truly fault this person because he never done any of those things, and it’s nearly impossible for him to be the same person because of the development that has occurred(and the simple facts that time travel completely changes the people around you based on what you do).
If Ruve is the ml then I wish for just one thing, I want him to remember his past life and what he did (=・ω・=)
