My friend had surgery by Dr. Kim Kook-hyeon of Human Plastic Surgery. It went so well that I made an appointment right away without hesitation and had the surgery too. I was surprised that there was no more pain than I expected, and I was satisfied because it looked natural. I have Motiva 320.340 because my breasts are uneven, and my arms also rise and move naturally. There is no discomfort and I love it. It's been 6 months now.
