Actor James Wolk has said that he has great chemistry with Adam Pally on the ABC sitcom Happy Endings.

The 26-year-old Wolk is guest starring as a former boyfriend of Pally's Max, the show's non-stereotypical gay character.

On Wednesday's episode, titled The St. Valentine's Day Maxssacre, Max runs into ex-boyfriend Grant (played by Wolk) on Valentine's Day.

“So Grant dumped you on Valentine's Day.” Alex says to Max as he drives his limousine carrying Grant and his date in the back seat behind a partition. “What did you do?”

“Nothing, literally nothing,” Max answers.

In a flashback, we see Grant surprising Max with flowers and champagne on Valentine's Day.

Surrounded by bags of chips, beer bottles and containers of take out food on the couch in his apartment, Max feebly asks, “Were we supposed to hang out today?”

“I double booked; you and this pizza,” he adds, pointing to a giant-sized pizza.

“So, you took Grant for granted,” Alex says.

The run-in creates friction between Grant and his date. Later he texts Max that he ruined a second Valentine's Day for him. Alex sees this as a sign and encourages Max to go to Grant.

“Come on, let's go get him, for love,” Alex insists.

In the episode's final sequence, Grant and Max are seen kissing in a horse-drawn carriage.

“Oh man, that is a handsome man!” Wolk told gay entertainment website “We had great chemistry. He's a great actor and a great guy and really funny and it made the whole thing really easy. … We wanted people to laugh, but we also wanted people to watch it and feel that this is a genuine relationship between these two guys. That was an important thing.”

Wolk will appear on two more episodes.
