It's been 9 years since I had double eyelid + epicanthoplasty in Seomyeon! From the beginning, I had surgery through an incision, but both eyes were uneven, so only the left eye had a double eyelid. The left eye originally had a shallow double eyelid line, but it was not strong enough to open after surgery . It was free!) The surgery went very naturally, so no one knows if you have double eyelids unless you tell them. If you want a line, I recommend it!
