What You Missed In Taylor Swift's Willow Music Video

What she meant became clear upon watching the video, which picks up immediately where "Cardigan" left off. Swift embarks on a dreamy, fairy-tale-like adventure after following a gold string back inside her piano. It culminates with her falling in love with Lee's character, after first spotting him while looking at her own reflection in a puddle. However, she then gets stuck inside a glass cage and can't reach him. 

Swift mentioned during a pre-release YouTube Q&A that one part of the video reflects her feelings on fame, and this would likely be that moment since she's trapped inside with everybody on the outside watching her. After breaking free, Swift sees Lee again but she has to follow the gold string back through the piano to finally meet him. The couple then quite literally strolls off into the sunset, or rather, sunlight, together.
