I'm looking for a specific fic that is from the point of view of Blaine's brother, with his observations on Blaine's life growing up, coming out and his relationship with Kurt. I think Blaine's brother and Blaine would play guitar and sing outside a store. Blaine's brother is getting married and Blaine brings Kurt to the wedding. I think Blaine's brother first meets Kurt in an airport when he is going to pick the couple up.
Thank you in advance for your help.
