We live in California and experienced an 18m lockdown. Unless you are using the experience to explain your absence from school the next year to briefly discuss your massive mental health meltdown or explaining that your grades declined because you were living in your car that year I’d let Covid go. Not because it wasn’t awful and hugely disruptive and changed your life and will mark you forever and you think you have something interesting to say about it. Because it did and you do. But so do a zillion other people and they have already said it.
As for, “rare” Asian and I have no idea if that is true. But although STEM is more popular in the US there are many Asian-Americans excelling in the humanities here.
I’d stress your other assets and really excellent EC and if you want to discuss specific pieces of writing I.e. maybe the extra pieces you submitted I think that is great. Good luck!
