On the 30th of June, a special episode of KBS's "Immortal Song" was aired for song writer Yoon Ilsang.

During the show, Ulala Session performed the song "I Love You Nuna" by Yoo Seungjun. Their performance to the remade version of the original song was powerful and each members' talents shone through.

After their performance, MC Shin Dongyup asked, "Do you guys really like Ailee?", and Park Gwang Sun shyly answered "I do like her". Park Seungil also replied, "I fell for her when I saw her singing on stage".

Even before their confession during the interview, the two members of Ulala Session had continuously expressed their interest in Ailee by making heart signs with their hands and dedicating them to Ailee backstage.
