Tezuka Productions Reveals Core Cast and Ending Theme in New Trailer for You Can't Be In a Rom-Com with Your Childhood Friends!

Anticipation is high for the 2026 anime adaptation of Shinya Misu's successful romantic comedy manga, You Can't Be In a Rom-Com with Your Childhood Friends! (known in Japan as Osananajimi to wa LoveCome ni Naranai). Generating significant interest ahead of its debut, the series has recently released a dynamic new trailer. This preview provides essential updates regarding the core voice cast and introduces the highly anticipated ending theme song, confirming that the romantic developments are progressing toward the premiere.

The adaptation is being handled by the venerable Tezuka Productions and centers on Eeyuu, a high school student whose life becomes complicated by a volatile love triangle involving his two closest childhood companions, Shio and Akari. While the setup suggests a conventional slice-of-life romance, Misu's narrative deliberately subverts typical expectations.

Despite years of shared history and intimate proximity, the transition to romance is depicted as challenging, marked by impatience, misunderstandings, and hidden secrets that complicate every interaction. The series title itself highlights the inherent difficulty of moving from platonic friends to romantic partners, adding a layer of meta-commentary to the protagonists' emotional journey.

The trailer effectively showcases the source material's blend of humor, heartfelt sincerity, and "twisted" romantic comedy elements. The original manga has established a substantial following, having been serialized on Kodansha's Magazine Pocket since March 2022 and accumulating 14 volumes to date. This strong foundation ensures the anime launches with an eager and dedicated fanbase already invested in Eeyuu's difficult decisions.

With Tezuka Productions' reputation for quality animation providing visual polish, excitement is building for how this distinctive take on the classic childhood friends trope will be realized on screen. The newly released visual and trailer emphasize the captivating character chemistry and the emotional depth beneath the comedic surface. Global accessibility is confirmed, as Crunchyroll will stream the series worldwide when it premieres in 2026. This latest preview reinforces the series' promise to deliver a compelling, humorous, and emotionally resonant exploration of the fine line between lifelong friendship and complicated love.
