That's My Atypical Girl

Synopsis

Taku Yokoi has trouble getting along with people, so he moved to Tokyo as soon as he graduated from high school. He now lives alone, making a living by delivering newspapers and drawing doujinshi, though people totally ignore his non-erotic works. One day, a girl named Megumi Saitou suddenly shows up at his door, claiming that she came all the way from Tottori to meet him because she's a big fan of one of his doujinshi. It ends up that she has faced many hardships herself, and with no intention of leaving, she ends up living with him.
