The story centers on Yu Nagami, a 15-year-old high school student whose dream was becoming a

professional light novel author. He has 14-year-old sister Suzuka. While she has both wit and beauty,

and is treated as a model student at her junior high school, she has treated her brother very coldly.


One day, Yu learns Suzuka wins the grand prize at a light novel contest, and to his surprise, the theme

of her novel is “flirtatious love comedy between an older brother and his younger sister.” In place of

Suzuka who doesn’t know anything about light novels and moe, Yu agrees to pretend as its author under

the pen name Towano Chikai. Even though it is a reluctant debut for him, Yu struggles to build up his

career as Towano Chikai for his sister. Then, Suzuka’s attitude toward her brother starts changing gradually…
