Well, I was watching the sprays of VALORANT and I saw that in Jett's spray, in the lower right corner something is written in korean

Jett's Spray. Korean text: 인사동

So I decided to translate it, when I translate this text, it shows a place. This place is Insa-dong (인사동)

Insa-dong neighborhood

This place is in the city of Seoul, South Korea. We know thanks to the player card of Jett "Mirrored Edge" and for a voice line, that she was a cook in a Seoul restaurant

Player Card \"Mirrored Edge\"

But when we look to the spray, we will see that also shows us the neighborhood where Jett worked, or the neighborhood where the tornado disaster happened

So before she got her powers, Jett worked as a cook in a restaurant in the Insadong neighborhood
