To Wear Heart Upon Sleeve by Evergreene
Although Agron and Nasir have grown close since the former slave gained freedom and joined the rebellion, one act has definitely gotten under the skin of the possessive and quick-to-anger Agron. Nasir has started wearing Agron's cloak without his permission, and he's at his wit's end. With a little help from Mira, Naevia and Crixus, Agron soon finds that only his possessions look best draped across his lover's skin.
This is a cute story that made me chuckle quite a few times. Agron shines with his irrational possessiveness of his cloak and Nasir is sweet, patient and kind, as always. I'm sure you'll get a kick out of this adorable one-shot.
