Review Detail of KaleKalum in Reincarnated as a Son of the Sword Saint and the Sage

This story starts off great. Has an interesting world and reason for being sent to that world, but damn the MC and family are a tough pill to swallow. The MC seems unable to stand up to his Sister or Mothers. If they even hints that they want something. The MC is falling all over himself to do it. The moment that killed this novel for me is when he told his sister about his past life and current skills. He tells her everything so he can potentially give his sister maid immortality. Since she wants to be with her forever. How does she respond to this knowledge. Threatens him with it and say that she need to put a leash around his neck. Oh and maybe sleeps with his childhood sweetheart and fiancée. tried to hate read the rest, but I just could get past the sister. Shame. It seemed like a nice novel.
