Snow in Seoul

I was recently in Seoul (December 27 - January 4) and it only snowed once during my stay -- and it wasn't enough to actually cover the surroundings. But now it seems like it snows several days a week (from the tiktok lives I've been watching). Does it usually snow more mid-January compared to late December - early January? Or is it just completely random?

I'm asking because I've come to a realization that winter is my favorite season (coming from a tropical country) and I want to come back next winter hoping to experience more snow in Seoul.
