You heard singing coming from the kitchen in your mansion so you got up getting a long pajama since Sebastian always puts your pajamas on for you, you got out of bed and left your master bedroom and got to the kitchen and poke your head over the corner and spotted Sebastian singing you were impressed while his voice was smooth

Sebastian: Take it with a piller of salt, halt! Its not my fault~ the devil made me do it but i also kinda wanted to

he felt a presence behind him but brushed it off
