The actress has spent seven months on screen as Kirsty Soames, who is the twisted fiancée of Weatherfield mechanic Tyrone Dobbs (Alan Halsall).
Gumede told Inside Soap: "Kirsty's parents will arrive in a couple of months and her father is a force to be reckoned with!
"Of course, nothing can justify Kirsty's behaviour, so I don't think the viewers will have any sympathy for her. Even so, it may give them more of a clue as to what made her the way she is."
As reported earlier this year, Kirsty will soon hit Tyrone during an argument as Coronation Street tackles the issue of domestic violence against men.
"The writing so far has been fantastic - things are set to get very dark indeed between Tyrone and Kirsty," Gumede confirmed. "It's nerve-wracking and daunting to play, but I do think it's a story that needs to be told."
Gumede is up for the 'Best Newcomer' prize at this year's British Soap Awards, which take place in London later this month.
