I like a guy that barely even knows i exist!!! :(?

I'm in 6th grade and I am like IN LOVVVVE with this guy named ryan! He's sooo cute and funny and sweet and he's the bestest!! I don't know what to do tho because I haven't even talked to him once this year cause I hardly ever see him @ school and I'm super shy around him!:( I really want him to like me and I'm think he did in like 4th grade but last year (5th grade) was the last time I taled to him! He used to think I was realllly funny and cool but now idk if he even remembers me!!! My BEST FRIENDS (kayla and olivia) ride his bus and I'm sooo jelous of them because they are really good friends wikth him! If I rode that bus I'm sure I would be too... but I don't and that seems like the only place I would have had a chance to try and get to know him before I started thinking about trying to get him to be "more than just friends" w/ him!!! :( I'm miss the days when we used to actually be friends!!! He was so cute when he would crack a joke in class or make a funny face @ the teacher... :'( is there any way I culd try to get him to notice me???? P.S... I am also not the most confident girl because I'm a LITTLE bit chubby but not really I guess cause I've lost like 5 pounds or whatever... anyway just please tell me what I should dooooo!!!! PPS olivia and kayla also know that I like him
