Siu

In 2017, Siu was introduced as a member of the upcoming boy group Challenger. However, he left the following year and the group canceled their debut plans in early 2019. On July 12, 2018, Siu was revealed as the last member of the boy group SAVE.

They were presumably disbanded due to inactivity on their official SNS accounts since the end of 2018, which were subsequently deleted. On December 21, 2019, he was introduced as the sixth member of DUSTIN. They then made their debut on January 6, with the digital single "Burn" and the release of their music video.
