[EDIT]For the people who commented or faved (or gave Tenten luv 8D), thank you so much! ^^
The song is 'Concrete Angel' by Martina McBride and is pure Tenten filler angst for her currently nonexistent background. T.T
For the curious, Tenten's name DOES have more than one meaning, and apart from 'heaven', I think the other ones are 'little by little' and 'here and there'.
Finally, lapse in judgement wrote a fic based on this on FF.net, called Concrete Angel. Go check it out, it's awesome. X3
