Glee has changed alot over the years. The genre-defying, boundary-breaking, fangirl-inspiring show has had its ups and downs — and so have the characters' relationships. If we're being honest, being a Glee shipper is hard: it's heartbreaking as often as it is thrilling. For example, while things are currently looking up for Blaine (Darren Criss) and Kurt (Chris Colfer), Season 4 was more than a little hard to take for fans of the adorable couple.

Sometimes it's nice to look back to simpler times before long distance, insecurity, and cheating came between Kurt and Blaine and nearly destroyed their relationship. So for this Flashback Friday, let's rewind all the way back to Season 2, Episode 6: "Never Been Kissed" to re-live the performance that started it all.

We're talking, of course, about Blaine's very first solo on the show: His unforgettably awesome cover of Katy Perry's "Teenage Dream," backed up by the Dalton Academy Warblers. After re-watching this scene, it's easy to see why Kurt fell for this insanely handsome, insanely charming, insanely talented man. It would be hard not to!

This performance became an instant Glee classic, quickly catapulting Blaine to fan favorite status and turning Darren Criss into a star overnight. Years later, it's still one of the most memorable Glee moments to date.

Relive the iconic performance here, and fall in love with Blaine all over again.
