September 4th of 2018 marks 2PM's 10th anniversary since their initial debut as a 7-member group with the song "10 out of 10".

At midnight on September 4 KST, the group posted a photo with all six members holding up the word 'Promise'. Although their anniversary exhibition '10 Seasons' has been cancelled due to controversy, fans online continued to support the group with the hashtag '#10YearsWith2PM'.

Member Junho also wrote a heartwarming message on his Twitter, one that thanked his fans, family, and fellow 2PM members. He wrote, "although things cannot be picture perfect even after 10 years, HOTTEST (fan club) will always be that one element which completes the picture as perfect." 

Check out the posts below! Congratulations to 2PM.
