In case you are not aware, readers, Koharu is Ui’s sister as describes in the lovely story “Peace Sign” by @koyuki-tan. She’s pretty great, and so is the story. https://archiveofourown.org/works/12422457?view_full_work=true
“Ooh, a melon bun.” Koharu eyes the bag in Ui’s hands.
Ui flushes on his way into his office. “Um…it’s not for you.”
“You just got enough for you and Hairuuuuuu,” Koharu purrs, hardly bothered. “Is tonight the night I’m going to become an auntie?”
“Koharu, shut up.” Ui slammed his office door in her face.
She knows she probably deserved that, but no matter. Koharu skips off to fill the rest of the beta-Quinx Squad in on Ui’s latest date ideas.
“It’s not even his latest idea,” Brooke complains. “Didn’t he do that two days ago, too?”
“Well, yes, but it’s cute,” Carma says quickly.
Michiko blushes. Mizurou and she often split meals in their offices. She finds it very romantic.
“We need to pressure that boy into proposing. Or at the least, confessing to Arima,” says Marie.
“Same difference, really,” Koharu muses. She wants Hairu as her sister-in-law. Hairu is good for Ui.
When Ui and Hairu finally emerge from his office – notably rumpled – Koharu grins slyly. Brooke winks at her.
“Shut up,” Ui mumbles as he passes Koharu.
“Koori, that’s not very nice,” says Hairu. She flashes a smile at Koharu. “Ui bought me melon buns again!”
“He knows you love them because he loves you,” Koharu says.
“Koharu!” Ui turns beet red.
“What?! You do. There’s no shame in my saying it.”
“I know, I just – Koharu – can you not -” Ui is too flustered to eek out a proper reply.
“I love him too.” Hairu turns around, and in full view of Koharu and her squad, kisses Ui.
In the background, Brooke holds up a camera.
