CloverWorks has officially revealed its adaptation of Sumiko Arai's manga The Guy She Was Interested In Wasn't a Guy at All, confirming a January 2027 release alongside a fresh teaser trailer and visual.

The announcement came through Aniplex at Anime Expo, where Crunchyroll confirmed it will stream the series. The teaser gave fans their first look at the creative team steering the project: director Masashi Ishihama (From the New World, Horimiya) will helm the series, with Rino Yamazaki (Spy×Family season 3) handling series composition and Kanna Hirayama (Oshi no Ko) designing characters.

The cast features Akari Kitō voicing protagonist Aya Ōsawa and Mariya Ise as Mitsuki Koga, the mysterious employee at a local CD shop who harbors her own secret.

Perhaps the most eyebrow-raising detail: the opening theme is Nirvana's 1991 grunge anthem "Breed." It's an unconventional choice for a romantic comedy anime that pairs well with the series' edgy yet charming premise.

The manga follows Aya, a fashionable high schooler who develops feelings for someone she thinks is a mysterious male CD shop employee—only to discover the person is actually Mitsuki, her female classmate who sits next to her in class. The premise cleverly plays with expectations and attraction, exploring what happens when Mitsuki must grapple with keeping her dual identity secret while growing closer to Aya.

Arai originally launched the series on Twitter (now X) in April 2022 before moving to pixiv Comic serialization. The manga has gained significant traction, ranking #2 on the 23rd annual Da Vinci "Book of the Year" list and placing second for top manga for female readers in the 2024 Kono Manga ga Sugoi! guidebook. Yen Press has licensed the series in English, with the third volume having released in December 2025.

With this creative lineup and the buzz surrounding the source material, the January 2027 premiere could be one of CloverWorks' standout releases that season.
