I'm curious about the surgery. Is it to make the eyes wider, bigger or to get a double eyelid?
If you make an incision you will only be cutting the skin that would create a fold, giving the double eyelid, but not stretching it to make the eyes wider. I don't know, that's my concept on what the surgery is, I never looked it up.
Airi is a very talented singer, nice dancer, and a great overall entertainer. if it's really a scar, then I can't say anything, what's done is done.
