I did it in ㅇㅎㅅ in Seomyeon, Busan, but the big swelling went away in a week, and since it's been a year, I've settled down with my current eyes and I'm satisfied so far. In the first place, the line was set small, so no one knows if it is double-sided. I think post-surgery care is really important for double eyelid surgery. Fighting everyone!
