Fox's Glade White Shadows

His chest tightens at her denial, and further when the tears start. For several beats, he's frozen, uncertain what to say or do — it seems he can only make things worse. But he has to try to help, right?
So he moves to press his nose tentatively to Korei's cheek if the gesture is allowed, only lingering briefly. He takes a breath as he pulls away, thoughts still scattered by the sound of her sobs. Korei — listen, He urges her gently, voice barely a murmur. Sometimes... sometimes a situation just isn't good for you. And — maybe it feels like you owed it to your family to stay, to try to make them happy. But you don't. Not at the expense of your own happiness.
You never left the Sanctuary, even when Lennon left — even when the cats came and everyone got sick. You've always been a loyal friend. Probably too loyal, He continues, nudging her affectionately with his nose in hopes of cheering her up. So I think you're strong for leaving your family. You weren't happy there — and no one is worth being miserable forever.
It's why Zamael had left him, and why he'd left the Sanctuary; it's why he'll never let any who share his blood back into his life, no matter how much it hurts. It's why he won't let Korei hate herself for making the decision she did. It's the one type of selfishness he can embrace in himself — finally.
