These two pictures don't really show difference except her facial expressions, the light, the hair and the makeup. It doesn't prove anything.
You say Suzy got a lot of surgery but where are your evidence? Do you have any proof of what you say? You say "everything is so subtle and soft that people wouldn't instantly notice" but then of course you noticed it because you have better eyes than everyone?
She is far from having got A LOT surgery. And if she had some surgery, it's probably not a lot like you say here.
And why would she do a lot of surgery while she has always been considered pretty by the public since her debut?
Suzy is pretty much natural.
She doesn't really need any job, her child photos clearly show it. Maybe (maybe not) she had some shots, but that's not PS. The only thing I know that Suzy has done is laminate her teeth and remove her baby hair but it's not surgery.
Sometimes it's just the angle of the photo or light or different faciale expression or even makeup or the quality of photos, who making slight differences... (or sometimes it's just that the person grew up or lost weight or gained weight)...
There is no real evidence that Suzy had surgery...
You can search other Suzy pics circa her debut, her jaw was pretty strong but suddenly it became small after her diet news. Imo strong jaw doesn't disappear by dieting, bcause it's bone, not fat. People with jaw fat have chubby jaw, not strong jaw.
Her jaw looks the same...
