They always say I don't understand love yet, that im too young, but they dont get it. The difference between liking someone and someone you can imagine spending you life with.
Little Riley Matthews, Maya Hart, Lucas Friar, Farkle Minkus and everyone else form a cute friendship and develop not REAL feelings but what they see as love from their young, innocent perspective. They'll grow and mature into young adults as the chapters proceed and begin to learn who they are.
