The idol shared thoughts on the great attention. At the showcase for Lovelyz' 4th mini album 'Heal' on April 23, Ryu Soo Jung stated, "I found out through the employees of my agency. The video of me with the outfit revealing my waist became a hot issue in online communities and social media." 

She continued, "It's the first time since my debut that I've gained attention like this. It's amazing and I'm happy."
