Without reading anything I've circled the candidates.

The reason I reject the others is smiling and having fun is normie behaviour. Being within sniffing distance of a girl, especially an attractive girl, is a no-no for /pol/tard incels in highschool (might improve a little later). Being directly in front of other people is also more extravert. Guy sitting down on the far right looks like he means business, as in a white collar/wagie type. Guy with the long hair in front of the "work is what you make it" poster is a little too normie. The girl with the single pig-tail on the right is the only potential girl candidate, but due to their extreme rarity and how it would be kind of a trick question if it was I'll rule that out.

Also this is a bit invasive, these are real people and I wash my hands of posting irl people on 4chan.
