Yuno Ogami

This is actually one of the good yaoi books out there. The two characters actually love each other and there is no rape involved. There is of course the back and forth between the "I can't see you because we are business rivals!" and "But I love you too much to be apart!"

The only downside of this book is Alex the fiance of Micah. She's only there to get between Yuuki and Micah before she's subsequently dumped by Micah. At least the author put in a small panel that she found happiness.
