Let us see... Sakura Haruno and I look similar to each other. The length of her hair before she cut it and the "big" forehead. I act a lot like her. [Can't अपलोड a picture right now,due to being on my phone.]
Azusa from K-On! is the only character I know of that matches me in both appearance and personality.
I don't like being lonely, and I don't like crying in front of others. But inside, I'm not as tough as I want to appear to be, and I tend to deny how I truly feel. We both want to be seen as mature, but are usually perceived as childish from our looks. I also appear calm, but I can snap easily when I'm teased. And I get embarrassed and shy and have low self-esteem. Lastly, because of my OCD, I think too much and worry about things.
I like Azusa's character because I really connect with her, and we're both misunderstood.
