Back in March, Seolhyun revealed that she's a huge fangirl of Taeyeon through 'Kim Shin Young's Hope Song at Noon'.

On the April 20 broadcast of 'Happy Together 3', she once again talked about her love for the sunbae idol and stated, "She's so cute and pretty. I told that to Kim Shin Young unnie. She then appeared on Shin Young unnie's radio. Taeyeon unnie told me to approach her more and not to be shy."
