I can only say this deserved the axe. If the mc only had fragmented memories of his past life (like 0,1% of the total) i can understand why this life would affect his personality completely. But apparently they were complete so I can't understand how the memories of a great sage(lived dozens maybe hundreds or more years, fought countless battles etc) wouldn't be his main part, the my lover killed so i have ptsd cant work on a "great sage". I dont wanna use my powers because they are a cheat so its unfair is also dumb, again a great sage that knows everything about life and its hardships wouldnt care about that.
Also all characters seem inconsistent, do they love the mc? Do they have some ulterior motive in finding him? Why do they try to kill each other despite knowing how op the mc is and how it would make him angry. Just bad overall.
