In Love<br>Chad had been friends with Will for thirteen years. He was basically family. The fact that Chad was in love with Will's sister caused a problem. He had basically watched her grow up from a child. Will just wanted Chad to be happy so he supported it after a while.
Chad and Will are related.
It specifically says they were friends for 13 years... I guess it is possible they were also family...
