A while ago, Lia and her manager, Ms. Shin, had made an arrangement with Sirens' manager from another agency, Ms. Park, to duet with them. Firstly, Sirens had an advantageous position, and a duet with them wasn't such a bad idea, even if Lia was more used to working alone. And secondly, this way, Lia could be closer to Luna and see her more often.

The song was recorded in a few days, but the music video still had to be shot. The atmosphere of the agency where Sirens worked gave Lia the creeps. While the idols at her agency at least communicated with each other, the PJK Endertainment agency was, to put it mildly, depressing.

Lia and Ms. Shin were sitting in Ms. Park's office, discussing what day exactly the first attempt at filming the music video would be. Ms. Shin did most of the talking, and Lia was only present.

Ms. Park: "I think we'll be able to film the video soon. Maybe even in a couple of days, if it's convenient for you..."

Ms. Park was interrupted by the entrance of two people. Aria and Yona entered the office without knocking. Without Luna. They looked very nervous, to say the least. Lia sat up straight in her chair, clearly unsure if there was any reason to be worried that would concern her. Ms. Shin and Ms. Park turned their gazes to them.

Ms. Park: "What are you doing here? Have you finished your performance yet?"

Sirens performed at a charity event today, and even though it was already over, Ms. Park was still surprised that Sirens came back early.

Aria: "Mr. Park... We have a problem. A very big problem. It seems so big that the filming of the video will have to be postponed..."

Ms. Park's voice became almost icy.

Ms. Park: "What problem could interfere with your work?"

Aria and Yona looked at each other with concern.

Yona: "We don't know the exact diagnosis, we need a doctor... but it seems like Luna broke a rib during the performance..."

Ms. Park: "A broken rib never stopped anyone from working."

Aria: "But Ms. Park, she can't walk on her own, let alone choreograph!"
