I Don't Like My Big Brother At All!

Second-year middle schooler Nao Takanashi dotes on her older brother, Shuusuke, with a full-blown brother complex. Determined to be seen as more than just a little sister, she makes a habit of flirting with him every day—teasing that sometimes catches Shuusuke off guard and sometimes draws him into playing along.

While cleaning out his room and tossing his adult magazines, Nao stumbles upon a childhood photo album that doesn’t include her at all. The discovery reveals an unsettling truth about their family ties, and instead of cooling her feelings, it only pushes her to cling to Shuusuke even more—until her hope of keeping him all to herself starts to look far less certain.
