Speculations started making its way around when Park Ki Woong shared on his Twitter on the 13th, "Our Ye Jin is currently #1 on 8 music charts! Please listen to and love Ailee's 'U&I' a lot so it can be on top^^ Ailee fighting!!!", raising eyebrows among those who noticed that Park Ki Woong used Ailee's real Korean name.

During a recent filming for 'Generation Sympathy Saturday', Ailee was asked about her relationship with the actor, and she responded, "I've never even met Park Ki Woong. I was also surprised upon seeing articles about him supporting me. I found out that Park Ki Woong is close friends with my manager and is a big fan of mine. So I'm very thankful for the support."
