Even if it ends up being a prank Bagi is doing on us. I think these detalis are interesting.
So, the base of the skin is Bagi's date skin. But there are some differences besides the red eyes
The shoes, besides the blood, seem to be a different color, or maybe they are dirty?
Bagi is also using what it looks like a wristwatch(maybe a bracelet with a dark gem?) on her left arm instead of the bracelet in the right arm, like the original.
The other cute detail is that, instead of her usual daisy, she has a pink flower, why is this cute? Well it kinda looks like she was trying to find a flower like Tina has on her hair, in her hanbok skin.
Her hair is also longer, you can see it both on the front and back
Also the buttons of her shirt are now dark gray instead o bage.
