In fifth place...
Noah Lawson and Hayley Smith (2004)
Noah and Hayley got together almost as soon as he arrived in the bay and despite a brief split where she went out with Alex and Josh and he almost got together with Kit and some girl whos name I can't even remember, it was quite clear that they were meant for each other. After an engagement, marriage was next on the list and things seemed to go pretty smoothly for them. With the death of her father, Hayley was understandably emotional on her big day but whilst getting out of the limo her father Ken was there waiting to walk her down the aisle. Noah saying "I love you Misses Lawson" was most definitely my favorite part of the episode and Hayley looked absolutely stunning. This wedding also went off without a hitch which probably earnt it extra marks and earlier that day, Kirsty and Kane had been enjoying their recommitment ceremony, so it was almost two weddings in one.
As a couple Noah and Hayley were good together and married life didn't pose too many problems for them but unfortunately their relationship was cut tragically short when Noah was shot dead by Sarah Lewis. Their fans will say that their love never really died though as a ghostly Noah returned to comfort Hayley through her grief.
