What Korean Schools should I look at for becoming a teacher?

So I have my heart set on going to college in South Korea because I wish to become a teacher there(preferably English or Math). I am nearly fluent in Korean but still have 2.5 years before I graduate, so I am confident I will be fluent by then, but I am having a hard time finding colleges that doesn’t have an acceptance rate of like 3%. My GPA is 3.9 unweighted and 4.7 weighted. I am willing to go anywhere in South Korea but would like to stay in Seoul. Any recommendations?

Any college with good programs for intl students would be a great fit. Maybe Yonsei of Ehwa? Yonsei is like the Princeton, Yale of SK. Other colleges in my opinions wouldn’t be a good fit for non-Korean students.

Good luck!
