Drarry (Draco/Harry)

The war was over. Almost all the students had returned for their eighth year to finish their studies. On one hand, Draco was glad. He would finally find his omega, whose scent he'd only smelled once before. In his sixth year, while he was in the hospital recovering from the Sextumsentra that Potter had launched at him, unaware of its properties. Draco was an Alpha with the scent of chocolate and almonds. His omega, and true mate, smelled of coffee and lavender. Draco had been trying to find the owner of this scent all this time, but to no avail. He hadn't even smelled it once since that incident.
Harry was a quiet, inconspicuous beta. At least, that's what everyone thought. In reality, he was an omega, hiding his scent very well. No one could detect it, not even the most sensitive alpha. Only his friends Ron and Hermione knew he was an omega. Everyone else thought he was just a beta.
After the war, Draco and Harry got along well. He, Ron, and Hermione even became very good friends with Draco's friends.

One day Draco accidentally bumped into someone - Sorry... - he noticed that he had bumped into Harry - Is everything okay?
