Would any of the characters be okay if we broke up with them? Or at the very least, politely and cutely rejected them?
Nope, absolutely none of them will be okay.
In fact it’s bold of you to think that’d they’d ever let you break up with them to begin with.

They are Yandere’s after all so here’s but a few categories of how they’d react.
1. They’d rather die (fall into depression and off themselves),
2. If they can’t have you no one will (they’d kill you),
3. They’d hold you captive (Stockholm syndrome),
4. They’d break your mind just to build you back up again (mind break),
5. They’d make you dependent on them (cripple you), 👀
Some reactions will vary from tame, moderate, or extreme in any case their darling ever brings up such blasphemy. Ultimately, It all depends on said yandere boi.
Since the Boss is a low profile kind of guy he actually just stealthily sneaks into the cafe that’s almost always booming with customers. Just to admire his precious idol while they work dressed in the cutest cosplay that always leave him struggling for life support. Reaping all kinds of mementos such as videos, photos, and even signatures once he got enough drive to ask you for some.
On the rare occasion that he’s not able to come to check in on you daily he sends in his right hand man the Enforcer along with the Hacker to do some innocent reconnaissance around the area you preside in. Telling them nonchalantly that it happened to involve a top priority client when the two hitman subordinates both knew that it was for his idol crush. The Enforcer and Yujin both just went along with the narrative their shy Boss was trying to push with knowing shit eating grins.
“Hey don’t you think we should help our poor Boss out with his idol crush? The progress bar hasn’t been increasing at all and it’s just so sad to see—pfft”
The Hacker snickered meanly with a catty expression on his face as he hacked into the surveillance cams to spy on you from beyond the screen of his laptop. The Enforcer could only laugh boisterously at his comment giving him a fist bump as he replied with an equally cheeky smile.
“Yup I totally agree man we should definitely try to help him out with the future missus, but we have to be discreet about it. After all the Boss is our top secret priority client~”
