Learning to cook korean food

Hello! 안영하세요!

I want to learn who to cook korean food. My boyfriend is korean and I want to surprise him and his family, specially his mother. Basically because Im from the Canary Islands, Spain, and I cant help going every day to a korean restaurant.I really wanna do it myself.

Ive been watching most of the videos but I dont know how to combine each dish. for example, if I cook 만두, what other dishes should I cook?

because in the korean restaurants here, if you order 불고기, you eat it with a salad, a bowl of rice and 반찬.

감사합니다
