Nagi and Kousei do a duet for Nagi’s school festival. Kousei starts out by taking it easy on Nagi and then he starts to challenge her. At first she freaks out because she already has so much pressure on top of her. But she doesn’t back down and the two of them create something magical.
Kaori is listening to it via a phone call from Watari. It does make her depressed at first but Kousei challenges her again by asking her to do another duet with him.
Nagi’s brother’s reaction is pretty funny because he’s Kousei’s piano rival and he’s being a protective older brother.
