Are those who had surgery using Sevin Serve really satisfied with the feel? My acquaintance says that even though 3 years have passed, the upper breasts are soft, the lower ones still look like firm cheeks... ㅠㅠ I wonder if it's a personal sex difference or if Sebin is a bit like that to begin with. When I actually touched it at the hospital, Sevin was softer than Motiva. ??
