(From Lililicious)
Flower Language is an original doujinshi from Sakuraike, perhaps better known for their Tact series. It features a very funny series of four-panel strips about a duo of girls (one straight, one gay) who draw yuri doujinshi together. It also includes a couple of other stories-- a short unrequited love story, and a longer story about a couple planning a double suicide together (which is actually much more upbeat than it sounds, trust me).

"Original" doujinshi by the circle Sakuraike.
