Hello I am looking for a manga/manhwa (not really sure what is it, its colored tho) Basically the sister was mistreated and her brothers and father got used to her just being their but they dont care about her and then she died and all of her family regretted it. Please help I have been looking for 2 hours already
The Duke or her father blamed her for his wife's death and so the brothers followed in his example since they were young by ignoring and treating her as if she wasn't there even though she tried so hard to gain their affection. Later on she ends up "dying" in a way because her physical body became a sword for generations until she was able to time travel back to when she was still living with her family. She ends up becoming an imperial tutor for one of the princes after coming back to ruin the empire as her revenge.
AHHHHHHHHHH
