Ryōta drags Kōsei to the hospital to visit Kaori, who continues to exhort Kōsei to keep practicing for the piano competition. During a rainstorm, Tsubaki knows that Kōsei loves Kaori, even though Kaori loves Ryōta. Tsubaki says that Kōsei should fall in love with her instead, only to kick him in the shin and run off in tears. The next day, Nao suspects something happened between Kōsei and Tsubaki, while Hiroko tries to tell Kōsei that he needs to concentrate on the piano competition finals. Kaori later contacts Kōsei to watch a late night flight in the starry sky. The following day, Kōsei admits to Ryōta that he likes Kaori, though Ryōta already figured as much. Kōsei and Ryōta walk towards Kaori's room, where nurses run in panic. They find out that her condition is drastically worsening as she seems to enter in cardiac arrest. Kōsei takes a dying kitten to a veterinary, but it is too late, seeing his hands covered in blood. He washes his hands and cries in agony.
