Girl in my 30's with a large dog. Looking to live in Seoul with maybe 3 roommates.

I'm new to trying to move to a new country. I am from the United States and I'm already in the process trying to get a Bachelor's degree here in the US. I would appreciate advice on applying to a Korean language school in order to be able to stay longer and of course I want to learn the language too. I'm thinking about moving to Seoul in August 2022, but I'm still working out the date. I don't care if living with boys/girls and if I can find a place that accepts large dogs. I only care about roommates who have patients with animals, who are not super messy, understands manners of our things, and people who want to go out often taking advantage of their time in Korea. I don't care about noises or the hours you keep, I'm easy going.
