Definitely King Halo and Nice Nature. King Halo of course for being heartbreaking the moment you learn more about her. As for Nice Nature, I just thought she seemed really boring. But then I realized what an endearing dork she is. And it really is hard not to root for her when you see how often she puts herself down as a defense mechanism.
Not quite as much, but I also came to like Oguri Rice a lot more after playing her story. Initially assumed she was more of an emotionless kuudere so it was nice to see her show more emotion.
