Post note: also, the consequence was dealt because Uno broke an established rule.
This is already ultimately different than the bottom getting random consequences because the top is angry for no reason at someone else (see Jaekyung from Jinx).
Uno knew it was a rule and very actively chose to ignore it in an established "working under me" dynamic. Again, this is different BECAUSE Enzo was already the owner in the first place. Uno was working UNDER him. Enzo set the rules because Uno CHOSE to work under him and CHOSE AGAIN to disobey it.

For the ones asking why people find this hot (or me personally): it's because this is a dynamic where they actually push each other's boundaries and test their limits, which is exactly what I'm looking for. (More explained below)
People were drawn in thinking they were "equals" but tbh this is a serious misreading. They never were. It has been imbalanced since the very beginning.
Uno literally only has himself and occasionally shadow. We see him complain all the time that he usually works alone and doesnt get any help anyway. He has what? 1 butler and 1 island. He's not specialized in close combat and his tools are primarily information gathering through seduction, and sometimes sniping from far away. His key skills are his people reading skills, and the way he can disarm people, making people vulnerable to his strategies with his charm. Without knowing any better, they allow him to steal information one way or another. He is primarily, an information thief, not a combat specialist.
Enzo on the other hand, has beyond far more assets. The Chicaro outfit. His own team. Businesses, land, entire organizations. People he can automatically call on to do his bidding. Not only that he is a very good combatant, extremely observant and especially versed in "traps". No one has ever stolen information from him that he did not already plan out himself to destroy or manipulate as pawns (see June). He traps people, and creates plays with very specific intentions, such as the murder of the organization members — this was already planned beforehand (see "merely their role"), even the "showing" of Umbra to the "connector" was also meant to be a trap.
They were never equals in the first place. But what intrigues Enzo to Uno is specifically because DESPITE all his machinations, Uno managed to slip through and take something that Enzo didn't expect. This is the precise moment when Enzo's "trigger" was flipped.
Enzo is a predator, and his primary instinct is to squish or kill. Which is why we see him TRY VERY HARD not to kill Uno (see when Uno gets roofied). He is giving Uno far more grace than he would any of his subordinates, who even despite working for him (see desert salon incident), he would kill, merely for getting his order slightly incorrect. We see this again when Arturo warns the squad chasing after Uno in the construction site, that if anyone makes an error on his order, it is them who will get a bullet in them. The restraint he shows when handling Uno is uniquely special. He even researches the dishes Uno likes to eat. He himself knows how dangerous he is. This is why he warns Uno repeatedly, over and over and over again (see trigger, cock usage, same "method", weapons warnings, etc). Honestly other people wouldn't even receive such a warning, they just get whacked with zero excuse (see June's information buyer).
Uno ignited a spark, and because Enzo's reservoir of gasoline was far greater than he had ever expected (see "we should have never touched them" vulture meeting). The team is caught off guard, Uno, especially. Yet DESPITE knowing this, he came back. Again and again and AGAIN. With his leash in his own hand, staying close to Enzo, precisely with the intention to fuck him over and get more information, instead of bailing like the rest of the team. This is honestly his own demise, he knew the gravity of it. Then to top it all off, he ignored Enzo's warning. That's why he is getting punished and being shown exactly what happens to those who ignore Enzo's command. Yet EVEN DESPITE THIS AND THEN, Enzo, yet again, gives him grace he would never do for anyone else (cock ring, instead of the grim alternative, that he would 100% have done given the authors confirmation of surgeons present).
The timeline of events was so:
Uno initiates (actor).
Enzo plays Uno (fountain incident)
Uno initiates again (connector)
Uno plays Enzo.
Enzo, baffled and surprised (trigger)
Enzo, plays Uno (information selling nullification)
Uno, yet knowing this, INITIATES AGAIN (leash)
Enzo, now interested, accepts the proposal.
Enzo warns Uno.
Uno ignores Enzo and does the one thing he asked not to do, simultaneously planning to use the information he has gathered to fuck over Enzo (video recordings of Via and consortium members)
Enzo, irate, traps Uno.
Uno weasles his way out of his getting his dick chopped, by acting subservient.
Enzo falls for it. Cock rings him instead.
Uno gets a lightened version of his punishment.
Based on these events, personally I think it's only a matter of time before, Uno once again weasles his way out of Enzo's machinations and steals something once more.
This is precisely the dynamic and tension I wanted, and why I love this series so much. Everytime Uno squirms and finds a way to sleaze through all of Enzo's traps, I get really giddy. And when Enzo does manage to catch Uno under his paws, well, you know, Uno actually does get a taste of getting devoured.
That's really hot. Especially the obsession.
I have never ever thought this was going to be a cozy little story where everyone is consensual and in love with each other. If it was, I probably would not have been as interested because it doesnt have this complex dynamic I was looking for. I read red candy, but it was a bit too ideal for me. Agent tries to get information from a dude, but turns out theyre childhood friends and they love each other <3 The end
Erm, sorry it's not AS interesting to me as Enzo and Uno's little game of tag. In this case Enzo being the big cat and Uno is a bunny who is surprisingly adept at getting away. How it develops from here and how much they can possess of each other, whether by trapping or stealing... that is what Im excited for and looking forward to.
Plus, Uno's little brat taming really tickles me (laugh)
