Summary
It was so unexpected to Rin; Akasaka Aria, the university student who'd temporarily acted as TA for her class, was also 'IA', the enigmatic new singer that the nation was buzzing about. What was even more of a shock to her was the kind of relationship that would blossom between the two as their new lives as colleagues went on. Truly unexpected indeed. (eventual) Rin K./IA.
