I think it kind of all relates back to this moment in September of 1950.
"On 29 September MacArthur restored the government of the Republic of Korea under Syngman Rhee.[96] On 30 September, Defense Secretary George Marshall sent an eyes-only message to MacArthur: "We want you to feel unhampered tactically and strategically to proceed north of the 38th parallel."
It was shortly after that they marched into North Korea and very quickly triggered a massive response from China. Ever since NK has been super paranoid about being invaded by land, air and especially sea. There were also a lot of good reasons why American and ROK forces did this too.
This topic though is speculation about safety not really about who is to blame. Old Kim Il is an evil dude who needs to go and his empire fall so the big reunification parties can start.

Back to the original topic. You are safe. It's been going on for over half a century with small randomn conflicts. I personally think it will go kablooey someday but most of the kablooey will be on the NK side. They have some numbers, old equipment, low morale, low supplies and every reason if there not to brainwashed to surrender.
My biggest worry if there was another bloody battle would be living in the local community. There would be bound to be one or two angry citizens shooting at foreigners. Otherwise keep your head down, hide if you can, run when you can and get out alive. The graves are full of brave souls who chose to fight but then again gotta do what you gotta do.

Anywho, no more war. It's good for nothing.
