Rosy has narrowed black eyes and messy black hair. He wears a simple dress shirt and dress pants, although on the pet shop mission with Dana, he was wearing a suit jacket. He stood at 179 cm (5'8").
During his first day as a SPOON Hero he and Dana were doing a pet shop inspection, wherein they saved Guineung.
He has a very light-hearted, sardonic personality that annoys his girlfriend but is familiar for Sasa. He doesn't appear to be very serious and wasn't surprised when he and Dana had found child Guineung as a pet slave-in-training. He can be serious at times when telling Sasa about Guineung's past, but even then, he teases Guineung when he sees him.
