Chicken Scratch Calligraphy

( Details within )
Emotionally gripping, funny as hell, and with more likable, three-dimensional characters than you can shake a stick at, I recommend Solanin to everyone. It's 28 chapters long, and the chapters are most short, so it's something that any of us can get through pretty easily. You can read it online at One Manga. It's also been licensed by Viz, who appear to have released it all in one big volume.
