So yes in her first life she died of old aged.
Second life she was reborn and while she did take her anger out on Luca he honestly didn't hate him deep down. After she found out someone wanted to kill him she went undercover and pretended to be on the evil guy side in hopes of protecting Luca. But she was found out and killed. Luca later learns this and in his mind she was the only one who loved him even though she didn't know it. This is why he is so protective of her.
Third life at this point in time she is remembering everything and as we know trying to fix past mistakes
