My Friend's Little Sister Has It in for Me!

友達の妹が俺にだけウザイ

Ooboshi Akiteru is a high school student who values efficiency above all else. He avoids deep relationships, has no interest in a girlfriend, and keeps only one close friend: Kohinata Ozuma. His quiet, unremarkable life takes a strange turn when Ozuma's younger sister, Kohinata Iroha, starts sneaking into his room using her brother's spare key.

Iroha is an honor student with top grades and a reputation for being kind and proper to everyone she meets. But around Akiteru, she is a completely different person: loud, pushy, and constantly annoying. She occupies his bed, tries to seduce him, and drags him into one troublesome situation after another.

As Akiteru tries to maintain his efficient lifestyle, he finds himself caught between Iroha's relentless teasing and the envious stares of classmates who only know her public image. His days become a chaotic mix of frustration and unexpected encounters with other difficult girls, forcing him to question the quiet life he worked so hard to build.
