LGBTQ+ YA novel out in early 2000s from 4 characters’ POV about a summer club.

Two of the characters were called Michael and Daisy. Michael was a gay teen with a straight best friend who was in love with him. Daisy was a lesbian whose girlfriend was away at a peace type camp.
I vaguely remember they all went to drama club/camp together and the 4th main character was a ‘bad boy’ type.
I read this in the early 2000s and I believe that is when it came out. I think it was set in the US.

Sorry this is so vague and thanks in advance for any suggestions!
