LONDON, Feb 14 (Reuters) - "Bridgerton" fans got a first

glimpse of the hit Netflix ( NFLX ) show's season four on Friday, which

will see a romance blossom between the noble family's second son

Benedict and a servant.

At an event in London, showrunner Jess Brownell joined

actors Luke Thompson and Yerin Ha to tease photos and a sneak

peek video of their characters Benedict Bridgerton and maid

Sophie Baek's upcoming relationship

"I feel like we spent the first three seasons really digging

into the upstairs world and getting to know the rules of the

ton," Brownell said. "So it felt right that after three seasons

of doing that we could expand the world out and go downstairs."

The Regency-era romance series is based on the "Bridgerton"

books by Julia Quinn, with each focusing on a sibling of the

Bridgerton family. The third season skipped the third book in

Quinn's series about Benedict to focus on his brother Colin and

Penelope Featherington.

But the next season, still in production, shines a light on

Benedict, who, long reluctant to settle down, becomes mesmerised

by a mysterious "lady in silver" at his mother's masquerade

ball.

"As a character we've got (Benedict) ... as sort of a little

musical theme for most of the seasons and suddenly it's like,

let's write a whole symphony about him and it's really

exciting," Thompson said of his character, until now a

supporting role, being the next focus of the show.

"It is going to bring a fresh energy and vibe to the show,"

Ha said of the new romance.

The actors were joined by co-star Golda Rosheuvel, who

portrays fan favourite Queen Charlotte. Asked what was in store

for her character next season, Rosheuvel said: "I think

discovering new avenues ... new friendships maybe and there's a

vulnerability to her that I think will be interesting to see."
