On April 7 KST, startup agency ATRP announced, "We are thrilled to announce that we have signed our first ever artist, Chuu. Please send your Chuu your attention as well as encouragements, as she begins a new chapter in her career."

An agency founded by former director Kim Jin Mi of WM Entertainment, ATRP assured that it would support Chuu to its fullest capabilities so that she could continue to promote in a comfortable, happy environment. 

Previously, it was reported that Chuu had signed with an agency known as BY4M after filing to terminate her contract with BlockBerry Creative. However, afterward, BY4M became embroiled in various controversies of its own, including false viral marketing.
