Seunghee explained, "I'm jealous of Hyojung unnie because when she sings the high notes, it doesn't look like she has any hard time with it. When I sing, people can feel 'she's singing her hardest/ardently'. But when she sings, she does it so well and effortlessly while maintaining her smile." Hyojung replied, "I used to sing children's songs a lot and because I have to simile while doing so, it's become a habit. On the contrary, I'm more jealous of Seunghee who sings so passionately."

Meanwhile, Oh My Girl have been actively promoting their latest hit "Secret Garden".
