In terms of “chancing” you, you really can’t compare yourself to the “average” person applying to any of those skills as your goals and skill set are pretty unique. Often different majors have different acceptance rates.
I would definitely check out Wellesley as long as you are okay with an all-female setting. They have both an Asian studies program and an art department that would be worth looking into. It’s not in Boston, but easy access. Excellent study abroad options (including South Korea) and internships. You can also cross-register for business classes at Babson. You can run the cost estimator to see if it might be affordable for you.
