Work Text:
For Ruby, the most graceful woman was obviously her sister, but Riko's presence was particularly beautiful. She was mesmerised every time she played the piano and she could only stare at her peaceful face whenever she played a melody she had composed.
Sometimes, if Chika was done with the lyrics, Riko would sing quietly and Ruby would listen to her all day long if she could. She couldn't put a name on that feeling, but the need to stay by Riko's side to spend more time with here was sincere. If she could, she would spend her life with her.
