Lee Hyori shared her thoughts on 'Pepero Day'. The singer wrote via her Twitter on the 11th, "Happy Pepero Day? I honestly have no idea what we are celebrating here". Even though Koreans have always celebrated November 11th as 'Pepero Day', this year is being called 'Pepero Day of the Millennium' as 11/11/11 only comes once every one thousand years. Various businesses are using the day as an excuse to promote and sell themed items, making it into a major holiday. People are voicing their opinions and saying, "I don't know why it's the day of the Millennium, its not every thousand years, but every hundred", "It's not even an important day like Mother's or Father's Day. They are making a big deal out of this, making us feel obligated to buy gifts for others". Netizens who saw Hyori's tweet commented, "I feel like we're congratulating the major companies that sell holiday goods", "I agree. My parents told me not to buy anything today", and "I think I may order some rice cakes and use it as an opportunity to do something nice for the community".

Pepero Day is an observance in South Korea similar to Valentine's Day. It is named after the Korean snack Pepero and held on November 11, since the date "11/11" resembles four sticks of Pepero. The holiday is observed mostly by young people and couples, who exchange Pepero sticks, other candies, and romantic gifts." - Wikipedia
