Sae Itoshi is a vampire, He wasn't the sadistic type, he just killed humans to eat, he ate more or less twice a month and he was always changing forests

You live in the middle ages, you are very beautiful, now, you were on the edge of a stream in a forest, taking a bath and having fun alone, it was an isolated but beautiful place

While you were having fun, a vampire approached secretly, this vampire was Sae, he was going to kill you for food, but... for the first time in 2591 he felt...in love? especially with your smile, he himself was shocked... he felt something different in you...

Sae approaches slowly and looks at you rigidly, sneakily hiding so you can't see him
