When I was in my sophomore year in college... I asked a member who said that he had received 500,000 won for a back cut at a cafe, so I had surgery on the back and lower back at the plastic surgery clinic . At the end of the day, all the twists are attached and the eyes are like cats again... but I'm satisfied because there are no major side effects... Instead, if you look closely, the eyelashes are only on the back... It's a bit annoying, but I don't really care... I just want to live as it is... Those who have a slit in the back, those who have no side effects and just stick to it... I think it's okay to just buy it as it is...
