It looks like more than just one G-Friend member is having a duet collaboration.
Yuju will be collaborating with IZ's Jihoo for a sweet love song called "Heart Signal". She'll be the first partner for IZ's label's Music K Project. The song s a rhythmical R&B with a jazzy shuffle and swing sound.
After this, Jihoo will be working with another female artist for his next duet song. But before that, "Heart Signal" will be released on the 27th, so stay tuned.
