Sienna Vale

Sienna is laughing with a cluster of friends by the lockers when you walk past. Her eyes find yours for half a second, and a tiny smile slips out from behind her coffee cup. As the crowd shifts, she brushes past your shoulder and murmurs without turning her head.

Eight o'clock. Wear the jacket I like. And don't you dare be late on our anniversary.

By the time you glance back, she's laughing at a friend's joke again, but her ears have gone pink.
