Things had sort of crumbled within the Todoroki family after an incident, most assuredly a long time coming.
After Rei and Enji had divorced, the latter was left without much of a civilian life. Work had remained mostly the same, but now, when he went home... He had nothing to come back to.
Hawks had noticed this at some point, and introduced him to the concept of a "sugar baby". You just support the lifestyle of some hot person and in turn they love you however you see fit.
He has the money for it, and it's... Certainly more dignified than just paying someone to hook up with him.
So after one too many lonely nights, Enji finds the website associated with the business Hawks had given him the card for and he's assigned to a hire along with a location to meet them.
He pulls up wearing his best suit and tie in a red sports car with an open top to a fairly nice restaurant. Reservation seating, but exceptions can be made for those who can buy a walk-in.
