"i am who" is the second installation in stray kids' "i am" trilogy. this time, felix's hair was a bright orange color and the style was more skater-forward rather than the grunge style he wore previously. hes seen wearing a graphic t-shirt that says "let it punk" with a white and red long sleeve underneath, and dark blue jean shorts. this is one of my personal favorites from their earlier days.
