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

I don't need any deep relationships. I have no desire for a girlfriend, and I only require one friend who holds any value to me. Ever since I threw out my youth for the sake of efficiency, there is one person who keeps entering the bedroom of Ooboshi Akiteru. She's neither my little sister nor my friend. She’s nothing more than a bothersome, annoying Kouhai, as well as my friend's little sister: Kohinata Iroha. "Senpai, let's go on a date~! Did you think I'd say that~?" Rather than blood, it seems that energy drinks run through her veins. She keeps occupying my bed, and she tries her best to seduce me with whatever method she can play to her favor. She's a girl who's constantly annoying and obnoxious around me. Even though I'm busy all day long, she doesn't care. And in case you're wondering why all these envious gazes are directed at me, it's because Iroha is actually really popular. She's an honor student at our school with top grades to boot, and she's known for being kind and proper to anyone she meets... Hey now, why are you only so annoying when you’re around me? ___ **Links:** - [Official Twitter](https://twitter.com/imouza_PR) - [Official LN (JP)](https://ga.sbcr.jp/sp/imouza/) - [Official LN (EN)](https://j-novel.club/s/my-friend-s-little-sister-has-it-in-for-me)
