Ai toka Koi toka Et cetera is a short but sweet little doujin about a girl who runs into the upper-classman she has a crush on on the way to school. There's not really much more that can be said without giving the entire thing away, since it's simple and the actual manga only takes up about 10 pages of the doujin.
Still, I found this story cute and enjoyable. It fit that cozy little niche many shoujo manga tend to fit into. The artwork that goes with it is also very cute and the artist draws some good expressions.
