Chapter 10:

Later, Ruka is thinking back to when Natsuki first got his ears pierced. It was soon after his accident, and he said that when he was diving he didn’t want to chance getting them caught on the diving hose, but now that he couldn’t dive anymore, he decided to do it. Then Fuuko calls to him, bringing him out of his thoughts. He brings her attention to a school of dolphins, and when she’s excited to see them, he suggests they get a closer look. He then shows her how to walk on water, saying that he’s sure she can do it, and when she can, he smiles and says even Natsuki can’t do that. Fuuko looks at him and thinks that probably he couldn’t treat Yumi this way just because he’s so aware of her as a woman(although Fuuko and he have actually ki8ssed) and, remembering how Natsuki said Ruka and Yumi are idiots, thinks that she, too, is afraid of asking Ruka’s real feelings. When they get back on shore, Fuuko remarks how impressed she is, and Ruka says if Occhan was here, he’d definitely take tons of pictures. Fuuko asks if he can walk on water as well, and Ruka says no, he would come by boat, and then asks if he hadn’t told her before – adults don’t ‘catch’ his power. Fuuko is surprised and asks why not, but Ruka doesn’t know. Fuuko starts to wonder if that means they’ll lose it once they grow up, when she notices Yumi getting hit on by some Tokyo university students. Ruka tells them Yumi has a boyfriend, and when they ask if he's the one, Natsuki shows up behind them looking pissed off and says no, he is. He also tells Ruka not to put himself forward so much, and when Ruka apologizes, he gets mad at him for that, which confuses Ruka. Fuuko thinks that since the cliff incident Natsuki has been irritated too. Then the guys challenge them to a surfing match, saying if they win, they get Yumi and Fuuko for the day, and if they lose, they’ll treat them to whatever they want. Fuuko agrees for the food and Natsuki agrees out of pride while Yumi and Ruka know it's a bad idea.

The contest is to see who can ride a certain wave the longest, and though Natsuki gets up first one of the university students knocks him down. Fuuko gets mad, and yelling that against a young opponent they're acting immature, she runs on the wave and side kicks one of them. Yumi notices that Natsuki is underwater too long, and sinking, Natsuki’s ear starts to hurt. He passes out, but Ruka saves him. When he regains consciousness, he hears Yumi saying it’s good that Ruka was there to save him, and he gets mad at Ruka, saying he never asked for his help. Yumi comments on his attitude, and Ruka tells him not to cause Yumi so much worry. Then Natsuki gets really mad, and tells Ruka their relationship is none of his business, if Ruka’s doing it out of guilt for the old accident, it’s getting rea;;y presemtuous of him. Everybody's feeling very tense, and Fuuko watches them. Ruka just apologizes, and Fuuko silently asks him why he’s apologizing, why Yumi’s not saying anything, and why Natsuki isn’t saying what he really feels, and from the tree above, Fuuko drops coconuts, surprising them all. She shouts at them all to be honest and say what they really mean, or else nothing will change the way it hasn’t for the past two years. Natsuki shouts that it has nothing to do with her, and she retorts that it does, because she likes Ruka, and right now she can't do anything about it because they aren’t moving forward. Natsuki then says to Ruka that he doesn't care who Yumi likes, he won't let her go, and Yumi slaps him! She tells him that of course the old accident still bothers her because she was afraid Natsuki might die, but she wouldn't go out with him just out of pity, and if he doesn't believe it now, they should just quit, and storms off. Ruka says he’s always known that Yumi only sees Natsuki, and he has something to tell Natsuki as well – that earring has never looked good, and Natsuki should give it up. Natsuki follows Yumi, and in the calm left behind, Ruka suggests that Fuuko come down out of the tree. Ruka tells her he always knew that Yumi likes Natsuki, because she told him about the underwater kiss and asked if she should tell him that she liked him as well. That’s when he gave her the necklace, it was a good luck charm for her and Natsuki. Back in the present, Ruka looks at the necklace and comments that it brings back memories, and he guesses Yumi doesn’t need it anymore. Then Fuuko, looking fed up, asks him where her answer is, and Ruka asks her if that kiss was serious. Fuuko gets mad, saying of course it was serious, and it’s horrible how he’s ignored it since Valentine’s. Ruka explains that he thought it might have been an accident because the balloon shifted, and then slowly says he’s sorry, but right now he can’t think of that kind of thing. Fuuko looks blank, and he adds that for now, he wants to stay just friends with her, but he really doesn’t want them to become uneasy around each other because of this. Fuuko is disappointed but she pretty much expected this, and thinks that she said the same thing before.

It cuts to Fuuko and Ruka in diving gear, Ruka’s already in the water but Fuuko is still in the boat, and she asks if this isn’t a bit sudden, her being a beginner and everything. Ruka says it’s fine because of her natural physical ability, and Natsuki, in normal clothes, kicks her out of the boat telling her not to be so chicken. Fuuko is annoyed but then forgets about it when she catches sight of the coral reef, with fishes swimming and Ruka waiting for her with his hand outstretched. She thinks that this is what all four of them have seen, and wonders if she’s come closer to Ruka with this.

On dry land, Natsuki tells Yumi she should have gone as well, but she protests that without him it would be boring anyways. He’s embarrassed and wonders if Yumi always said things like this, and Yumi asks if she can come up as well(Natsuki’s sitting on a rock hill). On the way up, she loses her footing but is saved by Natsuki who asks what’s wrong. She responds that since morning she’s felt weird, and she feels like her power is fading…

In the deep, Fuuko and Ruka watch the scenery, and Fuuko wonders if she can slowly become the person closest to Ruka…
