The Beads
Imagine that for orcs, the hair beads have a deeper meaning than just being an ornament.Just like dwarves, orcs have beads that are given by parents on special occasions like birthdays, by friends as tokens of comeradeship, after a battle to commemorate their bravery, and private beads given as a sign of affection.
Reader doesn't know of this and casually gives an orc warrior a hair tie with beads after redoing his braid - which for him means she want's to start a courtship with him ❤️
