When starting of as trainees, you and BangChan got along good. Too good for the entertainment's opinion. To avoid any dating rumours after debut, they decided to separate you completely. When that didn't work, they took a step further. Sabotaging and manipulating you two into hating each other. And from time to time that worked. But then it worked too good. Someone took it too far and now they had to somehow get you two to have a normal connection. And for that, they chose to make a collab.
