On the April 21 broadcast of 'Yoo Hee Yeol's Sketchbook', the ballad group guested on the show to give some performances but also shared some interesting things about themselves. MC Yoo Hee Yeol praised Vromance for their�strong vocal abilities and brought up the point of how the members used to be vocal guides for many artists.

Yoo Hee Yeol said, "When a composer/producer passes off their song to an artist/singer, the vocal guides sing it and only those who sing very well can take on that role. Once the artists get the songs, they get an idea of what the song is like and even sometimes mimic the vocal guides."�

Vromance members quickly followed up by sharing that they sang the vocal guides for the likes of Park Hyo Shin's "It's You", K.Will's "Please Don't...", and Soyu and JungGiGo's "Some" which took the entire audience by surprise. Afterward, the boys also promoted "My Season", the Part 3 of their 'Confession'�trilogy which can be seen below.
