Nick decides to pop the question to Leanne (Jane Danson) following some encouragement from Kylie Platt, who urges him to make a commitment to his partner.
Bistro owner Nick is blissfully unaware that a scheming Kylie isn't expecting Leanne to say yes. Instead, Kylie has secretly teamed up with Eva Price (Catherine Tyldesley) in a bid to split up the reunited couple.
Kylie believes that Nick will end things with Leanne if she rejects his proposal, but whether her plan will work out remains to be seen.
Price told All About Soap of the storyline: "Kylie suggests to Nick that he should ask Leanne to marry him, knowing full well that Leanne would say no. Kylie doesn't want them to be together, she hates Leanne! Leanne looks down her nose at Kylie and she wants payback."
He continued: "Kylie persuades him that Leanne would love it if he made a grand gesture and popped the question at the Bistro - but of course, that couldn't be further from the truth.
"Nick ignores all his own instincts and decides to go ahead with proposing to Leanne."
Asked whether Leanne will accept, the actor replied: "It's not likely. In fact, I think she'll react very badly. Nick is optimistic, though. He reckons if he asks Leanne to marry him in a public place then she won't be able to turn him down. But I think he's in for a very rude awakening!"
Coronation Street airs the proposal on Monday, November 19.
