In an interview with '@star1,' Subin talked about her new release "Ketchup," and solo activities. The idol star also stated, "I get many questions asking if Dal Shabet has disbanded but we have not."
She continued, "At the end of the year, the members got together and said it'll be nice for us to promote together again."
In December 2017, Subin left Happy Face Entertainment. In February 2018, she signed with the new agency Key East.
