Over recent weeks, both characters have been shown growing increasingly fed up with their other halves - Cindy feels neglected by Tony, who is spending more and more time with Rob and Barney, whereas Rhys feels alienated from Jacqui following dramas in the McQueen household.
Things come to a head after Jacqui accuses Cindy of flirting with Rhys and the women end up having a row in College Coffee. As Jacqui storms off, Cindy manages to accidentally start a small fire at the café and Rhys has to help her put it out.
After the commotion, Cindy announces that she feels faint and Rhys carries her to the sofa where they briefly kiss before being interrupted by Tony and Jacqui.
See the events leading up to the kiss unfold on Friday, September 21 on Channel 4.
