Manoban is the lead dancer, rapper, and sub-vocalist for Blackpink. She has been in the entertainment industry since her teenage days. It is fair to say she has aged in her years under the spotlight, which does have an influence over one's appearance.
However, netizens over on forums like Quora don't believe that all of the changes in appearances could be attributed to age alone.
One argument that seemed to be unanimous was that the rapper had several nose jobs done — not just one. They argued the songstress had rhinoplasties done to slim down her nose bridge, make the nostrils slimmer, and make the tip of her nose less bulbous.
They put forth that all of these modifications were not conducted in one fell swoop, but rather with a series of procedures over time.
They also presented Manoban's pre-debut photos and contrasted them against her current ones to highlight said claims.
