Bowman plays sixth-former Maddie Morrison in the Channel 4 soap, who has been dating Callum Kane (Laurie Duncan) for three months.
She explained that Callum is "really good" for Maddie as he keeps her grounded and calms her busy lifestyle down.
"Callum's really good for Maddie. He's quite an earthy character, and he really grounds her," she told MSN UK. "He's great for her and she can learn a lot from him. He sort of reins her in a bit.
"It's a big step because Maddie is such a head case. She gives off this persona of being the girl-about-town and pretty capable of everything, but she's really into Callum in a big way. She's really putting her heart on her sleeve."
The couple are set to end their three-month sex ban next week, and Bowman added that filming the romantic scenes were "easy" due to their real life friendship.
"I think it's easier to film scenes like that with people you know, and obviously I've been working with Laurie for a while now. You're just having a laugh and getting on with it," she said.
"But it's a funny feeling, getting up, coming into work and then putting your pyjamas on and jumping into bed!"
Scarlett Bowman recently told Digital Spy that she didn't think Callum and Maddie were a good couple as they were "too different".
