Although the narrative is not relatable, in the sense that I could count on my hands, how many people have been proposed to via illustrated gum wrappers. Yet it plays on scenarios that many couples can relate to like the first time they met, arguing, being a part for either work or vacation etc. In that sense it has a universal appeal because anyone in a relationship can identify with ups and downs and the idea of a peace offering to make things better again.
I think this advert was defiantly on to something, its clearly targeted at women both in relationships and single with that aspiration of romance and finding the one. What I feel makes it great is that its not too unrealistic they don't just show this whirlwind romance that flows smoothly. Showing times of adversity makes the relationship feel more real and attainable, so therefore more identifiable for the viewer.
