They look exactly the same but Swapping one's name was Jangwoo and here his name is Ha Taegeom from the text I think. He seems to be working under the old man president here.
I skimmed through the chapters of swapping and found that on ch19 MC was recalling about a construction case and bodyguard was the defendant but his boss was ML at that time too tho, if bodyguard was still working with Swapped ML at the end of that story then maybe this is the past? If they're the same person anyway.
What happened to him at the end? He was a minor character so I didn't pay attention. Do you remember the old president from anywhere?

Wait did the bodyguard really work for the old guy? In ch19 bodyguard said to MC that his boss wants to meet him in the car next to them, it was the ML sitting there tho. That happened right after the court case, I assumed he had have been working under the ML for some time.
There were too many old man in that manhwa I don't remember this particular one. Was Yeseung there too?
The bodyguard from swapping appears in cp 10 which means it's the same universe and potential side stories from swapping
