You can see very well Nana's change and wish for redemption, even after the change on his face, she still went in front of him to take the shoots instead of him, I hate how people in other sites just say she is a bitch who should did, someone who kill without any feelings, even after so long she stopped it, Nana's character is great, if you can't see it, you either don't care about the story or is one these 14-18 old project of incel guys who hate when the female character is not just a love interest and I don't know why kept reading if dislike it
