Isekai manga

Hello!!! Does anyone know that manga where the fmc was reborn about 4 times and she remembers all those times. And the exact same things kept on happening, she had a childhood friend who she loved and he loved her but he was destined to be the hero who kills the demon lord and tells her that he will come back for her except he never does. And so in this new life time she leaves the village after her childhood friend leaves because she already knows what’s going to happen. And turns out he remembers his past life times too and it wasn’t technically his fault that he never returned! And then they have to go fight the demon king who is actually the hero in the first life?! (Turns out they’ve been reborn about 7-9 times already but they only remembered a couple lifetimes)
