On the December 20 airing of SBS Love FM's 'Kim Chang Yeol's Old school', Soyu joined as the guest and said, "I'm introverted so I don't have many close celebrity friends." She added, "But I recently became close with Microdot after going on 'Laws of the Jungle'. And I became close with EXID's Hani who I'm currently working together with on a program."

Known as the 'Queen of Collaborations', Soyu was also asked, "Which artist do you want to sing a duet with?" She answered, "Nowadays, BTS' Jungkook's voice is extremely nice. Several days ago I named Zion.T and I think it'll be great if it really happens. Both of them are wonderful so it's hard to choose just one."
