JJ was already playfully irritated at Sooji's joke he had made. As soon as he heard the door open and he saw Sooji standing there, he immediately took a step into the penthouse and back Sooji against the nearest wall.
"Think you're so funny, don't you?"
sooji is proud of his jokes, giggling to himself as he opens the door for jj.
"hiya!"
he says, tail swishing behind him, one of his best friend's shirts being the only thing covering his body.
