A life.. that will repeat

My world has changed, when I woke up in this body, I didn't know, what would happen to me, so I just went on with the flow. I want to see where this goes, and if it can, make me feel, anything! “Wait is that.. her? and Why is she… here? What kind of mixed up world is this” Who knew, I’d find, love, pain, peace and sadness, all in one, goo ant messed up, mix of a world. It’s a harem and Mc, has an immortal background, but different from his past life, low key Op, red dust immortal realm, and he will have 8 partners, it is a mixed world and withering flower is one of them.
