When it comes to sweet, poignant shoujo, Kozue Chiba is my go-to author.
In fact, I once taught an entire classroom the proper way to read a manga with panels from one of her stories
If you've never read anything by her, but you like sweet shoujo, I highly recommend her!

It may get tweaked a little more before I can find no more faults with it, but I'm happy with it right now, so I thought I'd share.
