How can I be myself around the guy I'm starting to like?

I've known this guy for at least a week and I'm starting to have some interest in him. We have almost the same taste in music since we have a lot of artists in common. We also have the same love for creating stories and drawing the characters. I would love to get to know him and him to get to know me, but I'm scared he won't like all my sides. Like, my sensitive side, my affectionate side, etc.

How can I approach him without scaring him away??
