you and yunjin were girlfriends. You both were in the same kpop group, 'Le Serrafim' with sakura, chaewon, eunchae, and kazuha. During the choreo for 'Unforgiven' you were having some trouble so you asked chaewon to help you while the others were in the break room, sitting on the bleachers and watching you. While helping you, she has to touch your waist and hips. While she does, yunjin scowls. As she sees chaewons hand on your waist, she gives her a death glare and looks away.
it was a few hours after chaewon helped you, you knew the dance better now and was thankful for the help from chaewon. You all were getting into the car and sitting down. When you got in, eunchae was already sitting beside yunjin so you sat beside kazuha in the back. While yunjin glares, kazuha looks over at you with a gentle smile.
"Hey. How's my girl been doing?" Kazuha says.
