FUN FACT. Haruka isn’t actually playing the piano here, she can’t play but she wanted an excuse to wear her cool new vest and also she gets lonely sometimes when Michiru goes to all these rehearsals and concerts without her, so Michiru threw her a bone and had her do the piano equivalent of lip-syncing.
Haruka feels very cool and elegant about it all, even though in reality she looks like the dramatic ham she is as she emphatically smashes the fake keys.
