Honroukei Shousetsuka to no Romance ni Tsuite

Asahi's company suddenly went bankrupt and he found himself out of a job. He went out and got seriously drunk, and then he bumped into someone and passed out. When Asahi woke up, he found Yagami, his favorite novelist, sitting in front of him. In exchange for the necklace Asahi accidentally broke, he ended up helping Yagami with his work. Asahi was surprised by Yagami's personality, which was completely different from his delicate writing style, and he found himself drawn to the writer. But Yagami seemed to have someone he could not forget.......! A lovely romance between a mysterious novelist and a former child actor.
