Raul Castillo says it won't be easy letting go of his character on HBO's Looking.

HBO abruptly canceled Looking after its second season but promised a special to end the series.

The show follows the lives of three gay men living in San Francisco: Patrick (played by Groff), who came to the city to find love, Dom (Murray Bartlett), a waiter looking to fulfill his father's dream of owning a successful restaurant, and Agustin (Frankie J. Alvarez), who struggles with his art and relationships.

Season 2 ended with Groff's video game designer character Patrick questioning whether he should stay with his boyfriend Kevin (Russell Tovey) or pursue a relationship with Richie (Castillo).

“I think for me, the scenes with Jonathan are – maybe easy is not the right word – but almost fluid,” Castillo told xFinity.com.

“I'm able to drop in with him and there is an ease to our camaraderie and our relationship. I think that I don't have to reach for it. It's there immediately and I feel so lucky to have a scene partner like him because you don't often get that. Cast members have made clear how much they have enjoyed working together, which is why they've had trouble letting go of the experience,” Castillo said.

“It's not going to be easy to walk away from this character,” he said.

Castillo added that being on Looking has given him the “artistic family that [he's] always longing for.”
