This series is perfect because no matter what season you're in, there's an episode (or several, actually) for it. There's really no plot here. However, I will say that no other series has ever made me feel so nostalgic. You'll enjoy watching the children and relating their life experiences and friendships to those you may have known when you were young. This anime is lighthearted and silly. The character Miu really keeps things hilarious. She is adorable! The music on this series is silly and childish at times and heartbreakingly beautiful at times (particularly the ending theme, "Classmate"). I like to watch this series in spring especially with the windows open and a breeze blowing in.
