On June 9, Eli shared a handwritten letter through U-KISS' official SNS. He expressed great appreciation to everyone for all the love and support they've shown his new family. His letter reads as follows:

I am greeting everyone for the first time in a year with our 11th mini album! A lot of things have happened up until now, right? There were good news, but in my opinion they were more surprising and shocking news~ I always feel sorry toward our U-KISS members, and even more sorry toward KISS me~ Did everyone have a hard time because of me? The struggle is probably still ongoing, but thank you so much for always cheering me on, and loving the U-KISS members. Thanks to you guys, I was able to participate in this album. Also, I've been away from SNS, but you guys still came to my 'Simply' recording, worrying and cheering for me. I am greatly touched, and so thankful. I will work harder for you guys who have waited for this promotion. I am going to appear not only on music programs, but also on variety shows, and the V APP! Please look forward to it. To be honest, I am very nervous, and also a bit afraid. But since KISS me are cheering on for me, I will smile without worrying about others. I can do that right? Thank you. I love you guys!
