A Harry Potter Draco fanfic, first-person perspective, with Draco as the pursuing partner.
From the moment Sili Folai accepted the Honeyduke's sweet Draco Malfoy offered him when he was four, he could never escape that silent protection.
An ancient protective charm made him bear all of Draco's pain. The day the Dark Mark was burned into his left arm, he chose to bear it alone.
He went undercover in the darkness as a double agent, using Nonverbal Spells to deflect every curse aimed at Draco. He collected every green apple candy wrapper, never explaining himself and never asking for anything.
Theme: Protect the one you love and keep those around you safe.
