Where are the office leaders of three people sitting?

The leader should sit in the lower right corner of your photo. Back against the east wall, facing west. Because there is a window here. The leader is in the innermost and brightest place.

The other two people can sit at the west or east table. Sitting there looks more harmonious.

It seems that you really have a heart. Come on, don't care about the pay. Now work more, study more and exercise yourself. You are sure to do a lot.
