Today, I will write a review of the tune liner. It was about half a year ago, and I received it for 500,000 won for 3 times at an event place, but the conclusion was that I just wasted the money. The counselor said that it has changed and that it will get better if I get more, so the event is held until this month. They asked me to pay additionally, but I didn't do it because I couldn't feel any effect. Maybe my eyesight is too dull... I'll have to put my hope in In-Mode.
