Itsuki Hashima is a novelist who's hopelessly enamored with the idea of little sisters and is constantly surrounded by colorful characters. A world class genius and love-guru who's beauty almost seems a waste on her. A girl who's constantly troubled by her friendships, love interests, and can't even find refuge in her dreams. A ridiculously talented illustrator. Each of them have as many problems and worries as the next and they never have a dull day together as they play games, travel, and work together. From the same author of the famous I Don't Have Many Friends, Yomi Hirasaka!

Working hard or hardly working? Miyako has gotten a part-time job in GF Bunko’s editorial department, thanks to the recommendation of Itsuki’s editor, Toki, but she had no idea how much work it would entail. Wrangling manuscripts from troublemaking authors, modeling for manga (in the nude), providing inspiration for Nayuta (also in the nude), drinking parties, ridiculous demands from authors and editors...How will she hold up?!

Sister-obsessed author Itsuki Hashima is embroiled in a bitter struggle with his popular series Sisterly Combat. Between video games and mixed baths and cherry blossom viewing and making up excuses for his editor, he's slowly but surely making progress on his manuscript. Somehow, he and his unique collection of friends--Nayuta Kani, Puriketsu, Miyako Shirokawa, and his little brother Chihiro--manage to stumble through life together. And not only that, but his friend Haruto's series has finally gotten an anime!

Nayuta Kani gets serious. Itsuki and his friends want to believe they would never let confessions of love affect their relationships with one another. But beneath the surface, confessions change everything...Matters of the heart can alter the flow of a story, sweeping other characters up in the tide. Itsuki’s anime project is also making waves, but rather than add a refreshing twist to his life, it threatens to swallow him whole. Meanwhile, on a distant shore, Puriketsu continues his search for the girl with the “ass of the millennium.” Little does he know that a new development is about to flood his well of inspiration...!

A new relationship begins. Itsuki Hashima and Nayuta Kani are now officially a couple, finding success in both love and work. This new era brings changes to not only them but Chihiro, Miyako, Haruto, and (for some reason) Itsuki’s tax accountant, Ashley. Chihiro, meanwhile, has a new rival to deal with, while Haruto gets the full-court press from Ui Aioi, a beautiful rookie novelist who adores him. With Christmas bells ringing in the background, it’s a new season for the whole ensemble—but as they say, the more things change, the more they stay the same...

A WRITER’S DUTY...IS TO WRITE. Giving up on becoming the hero of his own story, Itsuki Hashima listlessly cranks out his tales like a light-novel machine. Nayuta Kani, meanwhile, has given up on writing entirely, holing up in her place and gaming as if her life depends on it. Haruto Fuwa and Miyako Shirakawa are flailing to figure out how to restore the duo to their usual energetic selves, but while the protagonists are frozen in time, the clock keeps ticking and life goes on—and life always has plenty of twists in store!

A LOVE TRIANGLE'S ALL YOU (DON'T) NEED. Itsuki Hashima, the little-sister-obsessed author whose novels feature nothing but his favorite character trope, presses on through day after frenetic day, despite all his trials and tribulations. Deadlines, love, even his own family weigh heavily upon his mind-but when his friend Haruto Fuwa (still reeling from the awful anime adaptation of his series) discusses a potential love interest, the results could shake up Itsuki's entire social life. Will peace prevail?!
