What is My Friend's Little Sister Has It In for Me!?
My Friend's Little Sister Has It In for Me! is a romantic comedy following Akiteru Ooboshi, a high schooler convinced that youth culture distractions are pointless—until his best friend's sister Iroha Kohinata makes it her personal mission to get under his skin. The series balances playful antagonism with genuine connection as Iroha's relentless teasing and clingy behavior push Akiteru out of his cynical comfort zone. Despite his protests that she's annoying, their dynamic hints at something deeper beneath the surface banter.
The series ran for 12 episodes during the Fall 2025 season, starting on October 5, 2025. This completed TV series offers a full story arc within a single season, making it accessible for viewers looking for a self-contained romantic comedy. The blend of slice-of-life moments with romantic tension appeals to fans who enjoy character-driven stories where chemistry develops through witty back-and-forth rather than immediate romance.
Akiteru's dismissive attitude toward typical high school experiences provides comedic contrast to Iroha's infectious enthusiasm and persistence, creating situations that shift between frustration and unexpected tenderness. If you're drawn to romance that develops through playful conflict and gradual emotional opening, this series delivers both the humor and the heart that make the genre engaging.
For high schooler Akiteru Ooboshi, the whole youthful experience thing—like fun, friendships, and even having a girlfriend—is a complete waste of time. So when his best friend’s sister, Iroha Kohinata, keeps teasing him, Akiteru naturally finds it annoying. She practically lives in his room, she’s always on his bed, she’s just a raging storm of clinginess! Why is she only annoying around him?! (Source: Crunchyroll)
