"Y-you gonna leave?" Ask Cynthia to with a sad tone, making the Demon's heart feels like it has been pricked by hundreds tiny needles. Crouching down to her level, Zehn gently pat Cynthia tiny head with his hand, making her already messy bedhair get even more messy.
"Don't worry, Princess, ill gone for only a few hours, tops. Your Papa need to help uncle Liam to fix some problems." He reassure the Elf with an apologetic smile on his face.
Seeing that his daughter still look a bit down, The Demon try to think something to cheer her up.
"Hey hey, how about a deal." He begin with a grin on his face, earning the Elf attention.
"Hm?" Was Cynthia response as she look at him with a curious expression. Making his grin widen a bit.
"I'll finish my work as fast as I can and when i return I'll give you a gift, a souvenir you can say. In return, i want you to be a nice girl and have some fun with Aunt Levi, how about that?" He finished with his best 'deal with the devil' tempting grin.
Cynthia eyes lit with excitement as the little girl ask him what her gift with an innocent expression.
"It's a secret, Princess, so do we have a deal?" He offered his hand for a handshake to the pouting Cynthia.
The little Elf stare at the offered palm before take ahold of his knuckle, she gently close four of his fingers into a fist one by one, leaving only his pinky, which she then connected to her much more smaller pinky finger.
"Em, Pinky promise..." She said with a firm tone before giving him a radiant smile.
