The actress's character Cheryl Gray, who made her first appearance three months ago, is about to come to the forefront of the Weatherfield soap with a domestic violence plot involving her husband Chris (Will Thorp).
Speaking on This Morning about the story, Quin-Ankrah admitted: "It was a bit scary really because I'd only just started. But it was brilliant to be given the opportunity to do a storyline like that. I'd never done anything like that before. It's quite difficult. I wanted to portray it right."
The star also admitted that playing a victim of domestic abuse has improved her knowledge of the issue and helped her to better understand why some women fail to leave violent partners.
She explained: "That was interesting because, getting the scripts, you start to understand why women do that, in a way. You always think, 'If I was in that position I'd leave him', but when you're reading a script, you are inside Cheryl's head."
Quin-Ankrah has previously promised that the storyline has many "twists and turns" to come.
