With the twins gone, Sana thinks he hears Shuri’s voice greeting him one morning, but it turns out to be just Nanaka. Sana also finds that rumors are now running rampant around school about Shuri and Shuusuke eloping, and he’s frustrated over how Shuusuke didn’t tell him anything. To his surprise though, he gets a package at home from Shuusuke containing fishing equipment, but he’s disappointed to see that there is no return address listed on it. On his way home from buying dinner at the convenience store, Sana notices Yuzuki sitting in a playground, so he goes over to talk with her. She explains that she’s feeling down about the twins because they knew that discussing things with her wouldn’t accomplish anything, so they didn’t say anything to her. Still, she wanted to at least encourage them. To make her feel better, Sana gives her a drink that he won at a drawing at the convenience store.
The next day, Sana decides to invite Aoi and Nanaka to the river again for another trip. However, when Sunday comes, he gets a call from Aoi saying that she can’t go because she’s sick. In truth, Aoi was faking it because she thinks it’d be better for Sana and Nanaka to go, just the two of them. When the couple reaches the river, Sana tries his hand at fishing, but he fails to catch anything. Fortunately, Aoi had advised Nanaka to make enough side dishes for two people to go with the onigiri they were already bringing. Nanaka is only able to cook tamagoyaki and bake cookies though, so that’s all she brought. Sana nevertheless finds it delicious and embarrasses Nanaka by saying that it’s because she made it. After eating, the two have some fun in the water before Sana convinces Nanaka to come with him because he has something he wants to show her. It starts raining during their trek up the mountain, but they soon are able to take shelter in the cave that Sana was aiming for.
The thing Sana wants to show Nanaka is further inside the cave, and it turns out to be sparkling minerals on the ceiling at the end of the cave. With Nanaka impressed because it looks like a starry sky, Sana explains that this was a secret spot that he shared with Shuusuke. Because they had promised to keep this a secret between them, Sana thinks that Shuusuke would be angry if he found out Sana brought Nanaka here, so he vows to apologize when he sees Shuusuke again. As Sana and Nanaka are enjoying this moment though, Sana’s flashlight suddenly goes out. Nanaka panics, but Sana stays calm and suggests they take shelter here until the rain stops. As she sits together with him, Nanaka decides to ask Sana about the wristwatch again. She still thinks that he got it from an old girlfriend like the others had suggested back during their previous trip, and while Sana denies that, he avoids telling her the truth about it.
Sana then asks Nanaka about why she put that letter for him in the secret mail box if she had really wanted him to come save her. Nanaka reveals that it was because she was scared since she knew that she had changed after the fire. She can’t even play the violin anymore, and for a reason she doesn’t understand, she gets a pain in her chest when she tries to pick it up. The doctor had told her that it might be connected to her lost memories. In any case, she had been worried that he’d changed too during their time apart, and so she put the letter in that mailbox to reach the Sana that she knew in elementary school. She realizes now that Sana didn’t change at all, so he’s still the Sana she knows, the Sana she loves. Nanaka falls asleep shortly after this, and when she wakes up, she’s by herself. Wandering to the entrance of the cave, she is momentarily blinded by the glow of the evening sky, and it triggers her memories of the fire.
As if in a trance, Nanaka walks outside and right over the edge of the short cliff that Sana is standing under. She doesn’t return to her senses until she’s falling, but fortunately Sana is able to catch her. Shivering in fear, Nanaka tells Sana that she remembers everything about the fire now.
If just seeing the sunset can make Nanaka remember what happened back then, why’d it take this long? It looks like the violin is the key to what happened though, and I’m somewhat suspicious of that violin teacher, if for no other reason than just because he’s introduced so late. Regardless of who is to blame for the fire though, I can’t help but wonder if it’s possible for Nanaka to get over it in just one episode without it feeling rushed. I guess we’ll find out next week…
In fact, most of my thoughts revolve around how they’re going to fit a good ending in one final episode. The preview shows that a good part of next episode will be flashbacked to Nanaka’s past, but there’s also the issue of Sana’s past and the wristwatch. I was practically yelling at the screen “just tell her already!” during that part of the episode because I know not covering that here means that they run the risk of making the final episode feel rushed by having to go through too much material. And that probably means that there won’t be enough time for Shuusuke and Shuri to make a return and wrap up their story in a good way. I think that the “ideal” situation for the entire gang would be that concert scene from the OP, and while it’s still possible, it looking less and less likely to happen.
