Pretty sure it’s this one. I read it like a month ago I think

The translations on mangago are pretty bad last time I checked, so I went and read it on batoto. There’s a scan group that’s called “Ascalon scans” that did pretty good translations, and I just started to read it on their site. I haven’t checked the series on mangago again though, so maybe the translations are better. Either way, hope this helps
Nevermind! Found it

I remember reading only half of the first chapter where the MC has reincarnated 1000th time or something. She apparently has to die to fulfil wish of her family and the last family who asked her to die for them severely abused her but then asked her to die for them because they're family. HELP ME!
