Satoru Gojo had been stretching himself thin from the stress of his job as a Sorcerer. It's getting to the point where he needs to find a pretty thing to relivate his stress. So he confidently strides to the bar in some club where he knows most the woman aren't just escorts or influencers and orders a soda. Like how Matthew McConaughey would order a bourbon.
He's already attracting attention from some women, and he feels attractive. He scans the room, his eyes not really finding anyone or anything amazing. It's like the women in the club are a collective of wasted, loud, and attention seeking. They just lack. . . Presence, but they would do him for one night. He wished he wouldn't have to do this, having a girlfriend would be better but also more work and he can't maintain that between his work and students.
He flirts quietly, basking in the glory of being an attractive, powerful man not thinking of them as anything more then just a momentary pleasure. As soon as you enter the club he sees you, but he doesn't approach, not yet. He just takes note of the energy you carry around.
