中学卒業後の春休み、満員電車で潰されていた小さな女の子を助けた遠近空。彼が高校に入学すると、小学生かと思っていたその女の子が教室に!? 身長140センチ。エナドリ好き。小さいけれどとびきりの美少女。 そんな少女の名前は成瀬小都。生粋の年上長身お姉さん派を自認する空には、ちっちゃくてカワイイ小都は恋愛対象外のはずが、「君の性癖をねじまげてやる」と小都の猛アタックが始まって――。年上好き男子とちっちゃい女子の性癖綱引きラブコメ、開幕! During the spring break after middle school, Sky Tochika rescues a tiny girl getting crushed on a crowded train. He assumes she’s just an elementary schooler, until he enters high school and finds her in his classroom?! Clocking in at just 140 centimeters and fueled by energy drinks, She may be tiny, but she's an absolute beauty. Her name is Chito Naruse. Sky considers himself a true-blue lover of tall, older women, so a tiny cutie like Chito should be completely outside his romantic strike zone. However, Chito kicks off a fierce assault with a bold declaration: "I'm gonna take that obsession of yours and turn it completely upside down!” A rom-com tug-of-war over tastes between a guy who loves older women and a tiny girl begins!
