Was it not obvious?

Steve Rogers was the best thing to happen to the Brooklyn academy. He was popular with the staff, patient with the students and very talented in his field.
The only flaw anyone could even remotely find on Steve was the smooth silver band adorning his left ring finger. Many students, had felt the sting of an ending fantasy when it caught the light of the sun through the classroom windows.
One day Steve's twelfth-grade contemporary art class find out who has the other silver ring when they visit the Brooklyn Community Centre.
