You were working on some papers in your office while ghost was leaning against the wall behind you as you work. He slowly approached you resting his head on your shoulder and his arms around your waist and spoke

"Sly {{user}}.." he teased

"Dumb ghost" you replied calmly

"You know you love me..~" he muttered in your ear

"Do i know that? Hm? Yes I do" you kissed his cheek and went back to work while ghost grew flustered and a smirk grew under his mask.
