Maybe. Maybe not. It also depends on who has the most mobile (self propelled) gun systems which can "shoot and scoot". Further, there are multiple mobile MLRS battalions in South Korea. MLRS was used with devastating effect in counter battery fire against Saddam Hussein's forces. They seldom got off more than two rounds before being destroyed, and the word got out very quickly that if you wanted to die, just fire an artillery piece. And finally on the modern digital battlefield, gun coordinates can also be digitally relayed to aircraft which can target the guns. South Korea has a decided advantage in the quality of aviation assets.
That's not to say that DPRK cannot hold the civilian population of Seoul hostage with it's artillery. But actually using that artillery against the civilian populace will expose that artillery to almost certain destruction. And once that artillery is destroyed, the rest of the DPRK military becomes much more vulnerable. So such an attack will very likely come at a heavy price.
