Hobo-1, if you're reading this and plan on continuing Spotted Flower, drop me an email and let me know. I'm just doing this because it looks like you've dropped off the face of the Earth. I tried to emulate your font choices so if you pick up from the next chapter, (probably) nobody will notice.
Anyway, if you read and follow Genshiken, you probably know what this is. If you don't, here's a brief summary: Kio Shimoku, the mangaka of Genshiken, is releasing very short installments of a new series, Spotted Flower,in the thrice-a-year magazine Rakuen Le Paradis. The story is about a married couple who totally are not Genshiken's Madarame Harunobu and totally not Kasukabe Saki, dealing with the events leading up to the birth of their first child.
Hints are dropped everywhere that the couple actually are Madarame and Saki, including in the title itself: the character "mada" as in Madarame means "spotted," while the character "saki," when used as a verb and not a name, means "to bloom." So, yeah. Nobody quite knows why Kio is doing this, but hey, I'm not complaining.
If this is your first introduction to the series and you're interested in starting, you can find the previous chapters easily enough online, both to download and to read online.
P.S. Bet you totally didn't notice that the imaginary son has the exact same hairstyle that Madarame has right now in Nidaime.
