Crush on Japanese guy

So there's this Japanese guy in my class and he's so cute. I have a crush on him and he's like my best friend and really hot. I don't want to come off as awkward though and need advice on that. Whenever I chill with him I feel like I'm just annoying him, but he doesn't look bothered. I know this isn't really a serious post and I'm just asking for advice how to act casual. All replies appreciated!
