One thing that is not utilized enough in Baam/Khun fics is the fact that Baam is generally shown a back sleeper that straight up does not move in his sleep while Khun tends to be shown more as a side sleeper and not only moves quite a bit but is also cannonically a blanket hog. If they were to sleep together, Baam is being used as the human pillow and may or may not end up with blankets and/or bruises from being kicked.
Ya know, at this point in the manga, Khun should really just put a tracker on Baam. A microchip, some sort of piercing or jewelry that most people wouldn't think to remove. He gets kidnapped, separated, hijacked? No sweat, two seconds, got him.
I don't condone tracking people, but it's a safety precaution at this point in the story. Lol
