Marianne (Daisy Edgar-Jones) and Connell (Paul Mescal) are really into each other. But they are very different people from very different worlds. She’s a rich girl from a cold, isolated family, and her classmates think she’s weird. He’s a popular, working class boy whose mother cleans Marianne’s family’s house.

So, obviously, they get together, but keep things on the DL.

“It’d be awkward if something happened with us,” Connell says in the trailer for Hulu’s “Normal People,” an adaptation of Sally Rooney’s novel of the same name. Marianne agrees, kind of. “No one would have to know,” she promises.

The two begin their quasi-relationship in high school and remain in each other’s lives for years. They share varying degrees of intimacy and, as the trailer underlines, have a lot of sex.

“We hook up, secretly. Like some kind of game,” Marianne says, explaining her and Connell’s connection to a friend. “That’s actually really hot,” her friend replies.

That’s how Connell sees things too, for all intents and purposes. “It’s so corrupt,” he remarks, “and sexy.”

Rooney penned the “Normal People” adaptation with Alice Birch (“Lady Macbeth”) and Mark O’Rowe (“Broken”) and also serves as executive producer. Hettie Macdonald (“Howards End”) and Lenny Abrahamson (“Room”) split directing duties.

All 12 episodes of “Normal People” hit Hulu April 29.
