Rothy

Kang Joo-hee (, born May 6, 1999), better known by the stage name Rothy (로시), is a South Korean singer. She made her debut on November 9, 2017, with the digital single "Stars". She was known as "Shin Seung-hun's Muse" by reporters.

Early life
Rothy attended Incheon Annam Middle School. She graduated from the Department of Applied Music at Hanlim Multi Art School.

2013–2016: Pre-debut
After auditioning in middle school, Rothy signed with Dorothy Company, receiving direct training from Shin Seung-hun for four years before making her debut. On her atypical idol training, Rothy said, "I went to a song camp, learned dance, and learned guitar. I focused on vocal training, but there were two teachers. I also received personalized one-on-one guidance from CEO Shin Seung-hun. That would be the differentiating point."

2017: "Stars"
Rothy released her first single "Stars" on November 9, 2017. "Stars" contains the story of a girl who is looking for her dream. Producer Shin Seung-hun said, "I'm trying to start Rothy with empathy. Knowing that she wants to sing songs that comfort her friends despite her age, she spent the last days of her teenage years looking for comfort and confidence in her self-identity and confusion." As a producer, he revealed his sincere wish, saying, "It's important to gain popularity, but I hope that people who sympathize with my song will find the reward as a musician."

After the release of the Face Live video for "Stars" through the M2 YouTube Channel, the single had a "chart reversal", ranking 3rd in real-time search terms on Melon, entered the Genie Music Top 100 and ranked 59th, and also rose 167 places from 368th to 194th on Melon, the highest ranking since its release.

On May 27, Rothy's second mini-album Color of Rothy was released with the title track "Bee". With Shape of Rothy representing a sketch, Color of Rothy represented color. This was Rothy's second song with a choreography after "Burning". Rothy said, "The title track, 'Bee', is a hip-hop R&B song that shows a very cute, chic, and bold side with lyrics that compare bees to flowers".
