Shitara is shocked to see Rin holding Mariho’s hand, but Rin quickly thanks her for giving him handkerchief and tells them that he has a headache so he will leave alone for now. Mariho asks him if he will be alright by himself, but he says he can always take a taxi. Shitara is disturbed and can’t believe this is happening. He starts franticly running to Rin even though Mariho and Masa tells them they’ll lose each other again.
After he catches up to him he takes his mask off (assuming he probably will be crying or something) but Rin, composed as always, teases Shitara with his tongue. Rin asks him why he chased after him a change a facial expression like that. He tries to change topic again saying his pain still didn’t fade away. He jokes with him saying he’s been teasing Mariho trying to seduce her, but he thinks he made her trouble because of that so he apologizes to Shitara for butting in. Shitara tells him he’s not a guy who would do that so he should just be honest with him. He asks Rin since when he was in love with Mariho. Rin is surprised by that and comments Shitara is so straight.
He continues he never said he likes Mariho and to be honest he is interested in her, since she is honest, strong and has what both of them lack, and looks like she grew up basking under the sun so he also feels warm while speaking to her. He tells him not to worry because he would never interfere with their mutual love, and he also doesn’t plan to confess her, so they should just wait to lose this feeling for her.
In the end he apologizes to taking her hand. Shitara is returning to Mariho and Masa, but looks like a world ended for him, since he feels probably like he just has lost a very precious person to him. While girls are enjoying fireworks, Shitara is remembering conversation with Rin, just a recent one when he asked Shitara where did he go on midnight and how he defended him in front of granny. Mariho bumps into him watching the fireworks and smiles to him saying it`s beautiful, but he remembers Rin saying to wait until feeling fade away and coldly agrees, what Mariho instantly notices.
The next morning, they were planning to go with Tomichan to river, but since it’s raining they should change their plans. Masa says they should be taking pictures and asks Mariho if she has any pictures with Shitara, just two of them, but she blushes and says she does’`t.
Masa tells Mariho to sit next to Shitara closer cause she isn`t fitting in the picture, so their shoulder touches, but just when she wants to take a picture, Masa says she will show to Rin this as well, so Shitara grabs her hand saying to stop cause he hates pictures and goes to watch TV, but Mariho notices something is off and becomes sad. Mariho asks him what’s wrong because he’s been acting strange since yesterday, but Shitara again indifferently tells that nothing’s wrong. She thinks how she doesn’t understand guys because he was so nice until 2 days ago.
Granny asks Shitara what is he doing and is surprised he is watching TV. Masa checks Rin out, wanting to show him pictures from last night. She tells him that Shitara’s been acting weird, he suddenly even told them he hates taking pictures when she wanted to take one with him and Mariho. Rin is surprised, since he thought Shitara would laugh and take picture with her and now he regrets telling all that stuff to Shitara. He asks Masa if she took only that one picture so she freaks out that there should be also photos from fireworks festival and them wearing yukata. Then, out of the blue, Rin says how he remembered the time when Shitara changed his facial expression. It was around the time they both entered an elementary school. There was a school event and Rin was obviously the only one that misheard the meeting place and was waiting there alone. Since he waited for a long time he thought to himself he was lucky for he could return home without having to participate in that. But then, little shitara with sour look as always, happened to run towards him and yelled at him not to run away. Little Rin was thinking through how he will talk with him for now, even though he didn’t really want to discuss how he was being left out by others, and then declared to Shitara he won’t run away. Shitara continued how he also doesn’t have friends but still, he won’t skip school. Then they laughed at each other. He tells Masa that Shitara is very frank and straight forward but bad at conveying that to others.
In the kitchen, Shitara asks Mariho if she’s already started doing lunch, but Mariho says it’s not but she is cooking udon for Rin in case he skipped breakfast. Shitara is obviously bothered and tells her that it would be better not being so nice to somebody else. Mariho is shocked saying it’s not somebody, it’s Rin, but Shitara tells her if he is hungry he can make something himself. She tells him she needs to take that to Rin, but he won’t let her pass, saying that it can also be cruel treating everybody nicely. She asks him what is he angry about and Shitara says nothing but that’s just how he feels. Then Tadaomi enters noticing they had a fight. Mariho is sad thinking how she didn’t really treat Rin special and wonders if it is her fault. She thinks how it’s gradually become harder to understand Shitara,
Then granny suddenly collapses. It seems it’s due to heavy things she was holding so the two take her to the doctor. It seems that once again Shitara is bothered that Mariho asked Tadaomi for help and not him. The doctor tells Mariho that granny strained her back and since she is old her recovery will probably be prolonged. Mariho decides she will stay there until she gets better. Mariho conveys the news to others and Masa asks her if she should stay with her to help but Mariho declines saying she can handle it.
Well since it means they won’t see each other, Shitara is gloomy again. She says Tadaomi will help her what makes Shitara explode of anger and tells her he will go home tomorrow as planned.
They are parting at train station and Mariho thinks to herself that since the incident she practically didn’t speak to Shitara. Rin tells Shitara that it’s time to stop behaving in such manners toward Mariho and it’s better to part in love way since they won’t see each other for a while. Mariho bids Masa and Rin a goodbye and stays alone with Shitara. They look at each other and Shitara asks her: “shall we return being friends?”
Mariho is shocked thinking she didn’t heard it wrong and she can’t make herself to ask why because she is scared that he’ll tell her he doesn’t like her anymore, but she tells him: “If that is what Shitara wants” He says “yes” and gets on the train, leaving a sad Mariho behind...
