I really hate the fact that other people saw her as erin not rin when erin herself acknowledge her (rin) as rin not erin. I also disappointed with grandfather, I know that he is a demon and all but I really thought that he adore erin as his granddaughter but I was wrong he is just doing those things because of the guilt that he has. I also the fact that ren is the ml is just feel out of place. I mean he saw her grow up and I just want him to be like her guardian and one of the reason why ren approached rin because rin he saw erin in her.
Don’t get me wrong I really like the plot and all . this just my opinion.
