Episode Summary: Yu has aspired to be a light novel author most of his teenage life, but his contest submissions never seem to make it to the finalist stage. After another rejection email, he looks up the winning entry – a story about a sister who harbors feelings for her older brother. Yu files the information away for later use (it might be a decent read, after all).
In the meantime, his sister Suzuka (with whom he has a strained relationship) begins to act as though she has some news to share with him. Finally he gets her to cough it up – she was, in fact, the winner of that writing contest, having submitted a manuscript that she just happened to write on a whim. With that blow to his confidence out of the way, Yu ends up undertaking a difficult challenge; Suzuka can’t make public appearances as an author for various reasons, so she ropes Yu into becoming the public face of her writing.
