Kym Marsh has spoken out about what’s in store for her character Michelle Connor on Coronation Street in the coming weeks... and let’s just say it’s not all good. In fact, she is about to find out that her partner Steve McDonald, who has been suffering from depression since before Christmas, owes thousands of pounds in unpaid tax. Speaking about the storyline, Kym told Digital Spy: "It’s a massive shock. Michelle had no idea there was a problem at all and she’s really troubled by it… but she’s reluctant to tell him for fear of setting back his recovery." She revealed: "Michelle and Liz check with the tax office and confirm the bill is correct. Michelle's gutted and she's really not looking forward to the prospect of breaking the news to Steve. "Michelle tries to go easy on him because she doesn't know how he's going to react and she doesn't want to send him into another downward spiral. She shows him the letters to see if he has any memory of the problem." Simon Gregson and Kym Marsh as Steve and Michelle. But that’s not all that’s in store for the couple as Steve decides, despite everything else that is going on, to pop the question to Michelle. Kym explained that it’s quite the shock: "She's stunned when he proposes to her. It's not what she is expecting at all and it comes as a bolt out of the blue." She added: "I think she does want to marry him but she's really concerned about the timing. If she is to say yes, she may suggest a long engagement. “She doesn't want to put Steve under any more pressure and she wouldn't want to rush things, but then she doesn't want to disappoint him either. I guess it will depend on whether she lets her heart rule her head!"
