On June 1, ELRIS held their debut showcase at Gangnam Event Hall. Ahead of her debut, 'K-Pop Star 6' runner-up Kim So Hee released her solo song "'Spotlight", saying, "We've trained together for three years, and I feel sorry for debuting first. My members supported me so much."
So Hee continued, "I am fortunate enough to get to be in a group and also be a solo. I liked being a solo, but promoting with my members brings me more strength and so I have no worries."
ELRIS debuted with their first mini album 'WE, First'.
