There's a oneshot at the end of a six- or five-chapter long yaoi manga. I don't remember either's name or what the longer one was about. But the oneshot had two guys who wanted to eat at a cake shop, but it was a couples only event so they weren't allowed in. So the non-black haired, more obnoxious of the two dresses up as a girl and the pair return. The waitress is skeptical, so they kiss. They eat and then decide to go out afterward. The end.

Does this sound familiar to anyone?

I know it's by Junko... Edit: Star-like Words ch. 6.
Also, you posted your request in the wrong section, yaoi/shounen-ai etc go to the Yaoi/Yuri section, even though it is a "I'm looking for..." request.

Got it, thanks!

I'm so sorry, but thank you!

Oh, it's fine. Just pay attention next time, because it is easier for you and for us, yaoi readers, to answer your request (if the title of this thread wasn't shounen-ai oneshot I would probably not even open it, because I look the sections in the right side).
