First of, Xander's thoughts ARE Xander. I hear him perfectly .

Secondly your writing is beautiful.

And lastly, the ending is wonderful. I sighed blissfully when their lips finally met in a mutual kiss, their unspoken declaration of love.

It's perfect as it is but I wouldn't mind, say a drabble from the first time one or both of them say it out loud :) look, I just don't want it end, alright! :)
