I donât 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. Sheâs neither my little sister nor my friend. Sheâs nothing more than a bothersome, annoying Kouhai, as well as my friendâs little sister: Kohinata Iroha.âSenpai, letâs go on a date! Did you think Iâd say that?âRather than blood, it seems like 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. Sheâs a girl whoâs constantly annoying and obnoxious around me. Even though Iâm busy all day long, she doesnât care.And in case youâre wondering why all these envious gazes are directed at me, itâs because Iroha is actually really popular. Sheâs an honor student at our school with top grades to boot, and sheâs known for being kind and proper to anyone she meets. Hey now, why are you only so annoying when youâre around me?
