Back then I personally got consultations at about 4 clinics in Gangnam before deciding. It felt like it took about 5 hours just to go around for consultations... But I had asked them to make it look as natural as possible. I kind of regret that. About a month after the surgery it looked like a hidden-and-visible double eyelid, but now it's almost an inner double eyelid ㅜㅜ I had epicanthoplasty and partial incision done. I regret not getting the outer corner surgery too. These days I'm looking into hospitals to get outer corner surgery.
