Coop and Phoebe first met when she accidentally bumped into him. Phoebe, however, did not even give him a second glance, which Billie brought to her attention. Later that day, Coop again came across Phoebe and told her he was her new neighbor. Phoebe being suspicious looked into his so-called apartment and found nothing. Later, when she confronted him he revealed himself to be a Cupid sent by the Elders to help her find love.

Phoebe's continued reluctance and Coop's persistence lead to them challenging, amusing and exciting each other. Phoebe also became comfortable asking Coop for advise and support.Coop helped unblock Phoebe's heart after spending the day time traveling looking over Phoebe's ex-loves. Coop then proceeded to find her perfect match. However, in the midst of it all, they both secretly fell in love with each other. They eventually admitted their feelings although the timing was a bit off as Billie and Christy had turned all magical creatures against the Charmed Ones. Coop, however, did not fall for the trick and professed his love for Phoebe to Victor in his search for her. When he eventually found her, she told him off due to being frustrated over the upcoming fight against Billie. Coop left but was called upon by Piper after Phoebe and Paige had died. Realizing Phoebe was dead, he willingly gave Piper his ring so she could time travel back and save his love. Later, when Coop met future Wyatt and Chris, Wyatt accidentally revealed that he and Phoebe were married in the future.
