A Pink released the M/V of Eunji’s self composed song ‘Promise U’ to celebrate their 4th Debut Anniversary. The M/V is made up of behind the scenes footage from the past 4 years. From the M/V we can see how much A Pink has grown through the past 4 years. The footages plus the extremely touching song is definitely going to make Pink Pandas cry with tears of joy ! Former member YooKyung was missing from the footages,however I am sure that she would be there in the hearts of A Pink and Pink Pandas! A Pink is definitely going yo grow even bigger and bring more joy to their fans in the future !
