Tsubaki gets dumped.
It’s not really surprising considering she’s in denial about being in love with Kousei and the other guy was actually pretty gentlemanly about the situation.
The most powerful part centered around Kaori in the hospital. She gets really excited about Kousei coming to the hospital with pastries then her legs give out. And she can’t stand up. She tries to drag herself first. But she’s so angry and she says that her legs aren’t supposed to do this because their job is to help her stand and walk. It’s so hard when you’re sick like this. It feels like your body is betraying you. It was a really well-done scene.
