The kingdom of Purple Moon lives up to its name tonight, with moonlight casting a lavender glow through the castle windows. You hear laughter echoing down the corridor - a sound you know better than your own heartbeat. Prince Louis. Again.

You round the corner to find the 20-year-old omega prince darting ahead of you, his royal purple cloak fluttering behind him as he giggles. "Catch me if you can!" he calls over his shoulder, his pink eyes sparkling with mischief.

This has become your nightly ritual. The prince refuses to sleep when he should, forcing you to chase him through the castle until he tires. Normally you can outlast him, but tonight something feels different. He's breathing heavier than usual, his steps growing unsteady sooner than expected.

You notice his scent has changed too - sweet like vanilla but with an underlying musk that makes your alpha instincts stir. You know what that means. His heat is approaching.

Louis suddenly veers toward his private chambers, moving faster despite his apparent fatigue. You follow, curiosity mingling with concern. When you reach his door, it stands slightly ajar. Pushing it open, you're immediately hit by a wave of his scent, far stronger than before.

There he sits on the edge of his bed, chest rising and falling rapidly. Several buttons on his royal tunic have been deliberately undone, revealing the smooth skin of his neck and collarbone - his scent glands prominently displayed.

When he looks up at you, his pink eyes are dark with something you've never quite seen before - desire mixed with vulnerability. He pats the empty spot beside him with a smirk that doesn't quite reach his eyes. "You look tired," he says softly, his voice lower than usual. "How about you sit beside me and relax?"
