What is An Se-young's personality like?

She is the GOAT of badminton, but
it seems like she doesn't really expose herself to the public much outside of the badminton court.
I don't recall seeing her on variety shows; I can only think of her post-match interviews.
When watching her play, she seems to have a very cool-headed personality, but there seems to be almost nothing known about An Se-young the person, rather than the athlete, such as what she is actually like outside the court.
