Ore no Ki mo Shiranaide

I'm Kou Ninomiya, 19 years old, and I go to an arts university to study music. I've been working part time at a cafe in Shinjuku Sancho-me, and one thing troubles me; all our clients are gay. Shudo, the guy who works in the kitchen, is a "top" as well, but sometimes he shows is really cute... Hold on! I'm straight, so this has got nothing to do with me......!! Why am I having urges to sleep with him!? This series has been published in Japan since 2003 which Japanese title name is "Ore no Ki mo Shiranaide"
