‘SuperStar K Little’ Sohn Yerim made a spectacular debut in the hot spotlight after about nine years.

On January 5, she released her debut single "PROBLEM" on various music sites at 6 p.m. and announced her full-fledged move as a solo artist.

Proving herself to be a "New Mainstream Singer" by ranking first in real-time search keywords on major portal sites after the news of her debut, Sohn Yerim released her debut song "PROBLEM" and is still receiving undiminished attention. In particular, the official debut of Mnet’s "SuperStar K 3" in 2011 when she was an elementary school student was made, which was followed by even greater public support.

Through "PROVALEM," Sohn Yerim showed the proud and confident charm of a 20-year-old girl. The music video, which was released, drew attention not only by showing off her cute and lively image, but also her sophisticated and colorful atmosphere. As the rumor of the formation was raised among netizens earlier, the appearance of Sohn Yerim, who has grown to be superior, has been admired.

The 171-centimeter-tall model-class figure was also more eye-catching in that it heralded the birth of a "giggy giant baby."

Another new song, "PALE BLUE," released with "PROBLEM," is a work that can be felt by Sohn Yerim only, and it is also receiving a good response.

Meanwhile, "PROBLEM," the debut single by Sohn Yerim, can be viewed on various music websites.
