Haru and Makoto are over at the back of the shop, discussing a magazine. Haru is educating him on the proper fit of swimwear.
"Hey, Haru," Kisumi calls, seeing Rin approaching through the window, "Fin's here, and…" oh, shit, now he knows why he recognises Kou.
She's Rin's sister.
"Mako," he warns, just in time, and they both look over to the door to see Rin bouncing in.
Gou slows, exchanging a long look with Makoto, who smiles, a soft apology for even existing.
Rin kisses Haru on the cheek, wet and cheeky, and nuzzles along his jaw to nibble at his ear. Haru grunts, a pleased little noise as he sets his hands on Rin's hips. Rin slips into his lap, arms around his neck, and Haru can tell he's tired, having switched up his sleeping pattern a little to spend some time with his sister during the evening, instead of going to bed after lunch to spend the morning with Haru. Rin grins, looking expectantly between Haru and Makoto.
"This is Rin," Haru introduces, squeezing around his waist to stop him smiling like an idiot, and looks Makoto over for any signs of discomfort.
Rin is clingy, Rin likes to show off their relationship, likes to cuddle up just as they would at home, and Haru's got used to him over the years, even if he still has to keep him restrained.
"Oh," Makoto deadpans, blinking. It must be obvious on his face, how he wasn't expecting this. "Oh," he says again, and rubs the back of his neck. "Rin, right. Unisex."
"You have a girly name too," Haru shrugs, and tightens his hold a little on Rin, and Rin feels him tense.
"And you have a girly name three," he teases, poking Haru on the nose. "Don't worry about it," he smiles, recognising Makoto from his visit the other week. He's in a much better mood this time. "Why don't you talk about me to your friends, Haru? This is my baby sister, Gou. She's been staying with us since her asshole ex left her."
Makoto squirms now, and Gou is just hovering by the counter, a bit too flabbergasted to even correct Rin on her preferred name.
"Kou," Makoto mumbles.
Rin and Haru's eyes widen.
"You," Rin is suddenly not in a good mood anymore. "You're the asshole?!" he splutters.
Kisumi, who's been having whispered words with Gou about just how awkward this is, interjects hastily. "Hey, Fishstick, that's my best customer," he warns to Rin.
Rin bares his teeth. "Can it, Smoochums," he grumbles.
Gou tugs at his sleeve. "We should just go…"
He's so obviously torn, trying to glare at this bastard while at the same time reassure his sister with a smile, and all the while sinking further into Haru to just save him. Haru kisses him lightly, just on the back of his neck.
"Go on," he says, agreeing with Gou for the first time in weeks. "I'll get some steak for dinner."
"Right," Rin mumbles, feeling considerably rejected. He demands a kiss, a proper one, hut just feels even shittier about the whole thing when Haru keeps his mouth firmly closed. "I love you," he says, begging, failing entirely at subtlety, but Haru isn't having any of it.
"I love you too," he promises, pushing at him to get up.
Rin's had it now. He leaves with a "whatever" and a glare thrown over his shoulder. Even Gou waits to pass them a soft smile before hurrying after him.
Haru sighs, followed by Kisumi, and Makoto tacks in at the end, resting his head on the table and letting it leak out into an unrestrained groan. Kisumi brings Haru water (because he knows how this goes) and runs a soothing hand up through his hair at the back, tussling lightly.
"Well that wasn't awkward at all," he says to break the silence, so thick with sarcasm it makes Makoto wince.
"I'll talk to him," Haru mumbles to Makoto, and gives Kisumi an appreciative look, saying it's ok. He drops his hand, leaving them to it. "I don't blame you," Haru continues.
Makoto grunts, eyebrow cocked in question.
"For dumping Gou," Haru shrugs. "She's… annoying," he decides is the word. She could be worse, yes, he does care about her, quite considerably, but she's too much like her brother, except he doesn't fancy the pants off her to make up for it.
"She dumped me," Makoto explains, exasperated.
"Why?" Haru asks, because really, just why?
Makoto shrugs. He's still stewing the whole safe thing over in his head.
Haru buys steak, as promised, and hands it over to Gou to cook and goes to find Rin napping in the bedroom, flat out on his front and sprawling everywhere, blanket slipped down to his hips. His top half is bare, but Haru can see the red of his boxers peeking out. He sits down on the bed next to him, and Rin wakes enough to move his head into his lap.
"I'm angry with you," he tells him outright.
"I don't even care, Haruka," the full name said with an obvious frown. "This is my sister we're talking about."
"He's my friend. And he's done nothing wrong."
"Don't you even care about your own family?!" Rin demands. He rolls away and sits up beside him, both looking down at the deliberate space between their legs, where they would usually be all tangled up. "You can't choose him over me."
"I can if you're being an idiot," Haru spits.
"But Gou –"
"Can look after herself. She finished him."
"I don't even care, Haru. Since when did you get so pally with this guy? And you didn't even tell him about me."
"He's always known," Haru says, honestly and quietly.
"Yeah, you just didn't want your new bestie to know you take it up the ass! Why aren't you proud of me?!"
"I am proud of you…"
"Whatever, Haru. Since when do you even have friends?"
Haru skips dinner in favour of a swim. He's supposed to be checking out another flat with Gou in the morning, and then they're both going for dinner with Rin in the evening.
He heads off to Kisumi's as soon as Rin goes to work.
