The guy in the black jacket - annoyed, uninterested, fashionable (he frowns and doesn't seem to enjoy the party, but he looks dressed well, so he cares for his appearance)
The girl in the jumpsuit - bored, shy (she doesn't talk to anyone and instead plays with some paper to not bore herself )
The boy with the glasses - smart, concentrated, (he is dressed as the typical 'geek' , he plays with the straw of his drink and seems to think about something)
