Korean ‘buns’?

Annyeonghaseyo Maangchi! My name is Naomi, and I have been a follower of yours for a long time! I have made sooo many of your dishes, own both cookbooks, etc.. I am half-Korean and half-mutt 😆!
There is one dish that I crave sooo much! Everytime I went to the outdoor market, near my late grandparents village, there was a stall that sold 2 kinds of buns. One was a kimchi and pork(?) Bun, and the other reminded me of mandu filling. We used to buy a bunch to eat while walking around, and a bunch to take home with us.
Could you make a recipe on how to make these 2 versions of savory, fluffy goodness please? Thank you!
