Nero's Manga

I really like this story but it makes frustrated the fact that she won't move on from her past life. I mean ofc she can't just forget about it, but it makes me sad she doesn't show barely any emotion. I believe that if she would just confid to the ml or anyone really (you know, her having a lover that she killed by his order, not exactly telling him she was reborn, that may a bit too much), maybe she could move on from her past and actually LIVE her present life and cherish it, because she doesn't really care for her own life since it's her second one. Our ML is just so cute that I feel sorry for him, she put up some really big walls around her heart and only stays with him out of simpathy, pity (maybe) and because he resembles her old lover, I don't care how many chapters it takes, I want to see real love displayed by her once more towards someone other that her past lover
