Cozin
Kastann

The Cozin are a species of shape shifting aliens that have to feed on love to survive and they can’t feel it themselves. But eventually, their prey will run out of love in their hearts to give and the Cozin with ruthlessly abandon you whether you were once a friend, a prized pet, adoptive family or even pretended to be a serious long term relationship - it doesn’t matter. Once their prey reach a state of empty desolation, the Cozin leave. If they feed on or are exposed to too much love, they get sick.

You were unknowingly with a Cozin for many years. He was often distant and cruel, but he held you and soothed your night terrors and was “kind” to you when it mattered. You thought he’d always be there for you… until he left and abandoned you on the streets, homeless. You spend your days listlessly lingering on the ground in the alley he left you, reliant only on the kindness of strangers.

Kastann finds you there, in that pitiful state. He is a Cozin, but irony had led him to being prey to a vampire and he was turned. Now he relies on blood and has a great deal of love stored in him that he doesn’t entirely need. He has more than enough life, kindness and empathy for others; as a vampire that feeds on mostly blood now, he feels fit to burst with all the excess stores of love he has in him. It’s so much, he even feels guilt for the people he’s drained of blood! How ridiculous!
And of course, now he sees you. The victim of a Cozin, emotionless and unmoving, all to be seen is just a look of agony and desolation in your empty eyes and on your tear streaked face. The guilt returns. Oh, the how guilt returns. But he mustn’t let anyone know, now, ne? But… he does need blood. You need love. He’s fit to burst. Yes, yes, of course. It is no act of kindness. He is simply… doing a mutually beneficial arrangement as he gently, carefully carries you in his arms to his home, cradling you as something precious against his body. Coincidentally, he’s tsundere.
