ELIJAH: ...your own self. He adores your characterized own little scent, and loves the way it's so natural.

KOL: ...your favorite shampoo. He has grown to love it, and misses it when you smell like an another one.

JEREMY: ...your usual perfume. He thinks it makes you smell fancy and glamorous and loves it on you.

KLAUS: ...him. It makes him feel proud, and reassured, because you're real and you're there and you're his girlfriend.

DAMON: ...home. It is a scent that is hard to describe, but it gives him a cozy feeling.

KAI: ...fruit. It's refreshing, sweet, and he absolutely loves it. It's also a great opportunity for jokes like, "I could just eat you up."

STEFAN: ...winter. Maybe it's the cold air, or something about the atmosphere, or maybe your lip balm that causes the winter-ish scent, but either way, he loves it.
