Help finding a doujin please.

Sorry that I can't describe it very well but I recall the art style was rather slender rather than voluptuous. It was a bunch of stories interacting with each other and it was set in college. I recall that one was about a guy and a foreign girl who needed his help with studies, and because of a misunderstanding he thought she had exchanged sexual favours for help with someone else (who he thought was a guy but was a girl who liked guys clothes.)

I also recall that the last story involved that girl as she was picked to play the lead heroine role in some play and started going on "dates" with a friend while wearing lots of different outfits and wigs, this led people on campus into thinking that guy was a playboy.

If anyone knows what the name of that doujinshi is then please let me know.
Thank you.

How long ago did you read this?

I think it has been quite some time. I can't really remember. A few years at least. It just popped into my mind recently.
