Hanimero

As an anonymous erotic author, high-school student Mitsumaru Yahiro needs to keep his occupation a secret. If anyone were to find out, everyone would look at him as a pervert and his life would be over. Yahiro's wish for his secret to remain unknown is reinforced when Kisaki Madoka, his crush, becomes disgusted when she saw his erotic series. Soon after, his work load increases and the publisher sends an assistant to help in the process. But the assistant turns out to be Madoka and, in fact, she is a giant fan of Yahiro's work. She seems to be willing to do anything to keep working for him and it looks like the tables have turned for Yahiro.
