Amaya Yu
Little sister to Jin-ho and Nori's twin. Takes after their father in personality in that she's more on the quiet side; tends to listen more than talks. Enjoys partaking in drumming and dancing to be close with her brothers, but her real passion is in remixing, editing, and cinematography. While she is a caring person that loves her friends and family a lot, due to her quiet nature and bluntness, most people she meets things she has a very blasé attitude at first.
Meets Shin through Jin-ho's musical career (she and Nori get to go with him and hangout during photoshoots and the like now and then) and they end up becoming close friends before eventually becoming a couple.
