I feel like Leonard does care for her as a little sister but because she was so mean toward Yvonne in the beginning he couldn't express his feelings well so it turned more into hatred but now it's somewhat easier. I'm really curious what'll happen when Yvonne comes back tho cuz I don't want them to treat her like nothing after they started caring for the "villainess" like in other stories but I don't want them to treat our female lead badly either. I'm very curious how it'll turn out!
