Ani ni Tsukeru Kusuri wa Nai!

Shi Miao would like a dependable older brother. What she has is Shi Fen, whose laziness and ridiculous schemes keep turning ordinary school days into arguments. Being only a year apart means there is little chance of escaping one another, and his latest provocation rarely goes unanswered.

Friends, food, schoolwork, and budding crushes provide fresh opportunities for embarrassment. Yet beneath the bickering, the siblings still look out for each other. Shi Fen's efforts to help may be disastrously misguided, but his sister keeps discovering that getting rid of her troublesome brother is not quite what she truly wants.
