On December 4, IU revealed a new episode of her YouTube show 'Palette' featuring KARA.
When IU saw the members of KARA entering the venue for her show, she excitedly greeted them.
Not only did IU frequently promoted with KARA around the same time in the past, but she also featured in SBS' television show 'Heroes' (2010) and hosted SBS' music show 'Inkigayo' in 2011 with Nicole.

At that time, IU said to Nicole, "Unnie! If it wasn't for you and KARA unnies, I would've felt so lonely today. Thank you for taking care of me as if I was a member of KARA. I really felt like one! We have a tough schedule coming up, but let's get through it together! I'll get through it like how you energetically do it, Nicole! See you at 'Inkigayo' on Sunday!"
To this, Nicole replied, "My sweet IU! I'll take care of you at all times! Always come to me, okay?! Have a safe journey home and take a good rest. See you on Sunday!"

IU responded, "I feel pretty similar to how you feel now. For me, KARA has always been 'warm'. That was my impression of you guys."
IU's words made Nicole tear up, and IU also teared up seeing Nicole wipe her tears.
With teary eyes, IU commented, "Nicole has always been loving with a soft heart. The reason why I wanted to have KARA on 'Palette' was because I'm a huge fan of KARA and I wanted to show my support for the group."
She continued, "When I made debut, I didn't get much attention from the public. It took me some time to get to where I am now. Back then, KARA was my 'hope'. It was because KARA was a late bloomer; KARA slowly caught the eye of the public, like myself. Since I've witnessed KARA succeed like that, it really got me thinking, 'I can do it!'. I'm sure KARA gave 'hope' to many K-pop artists, not just myself."
