I can suggest Le Coup De Foudre. It is the second lead that is the writer, though. 

Did no one mention Romance is a bonus book?

The Inerasable (Zan'e) - Japanese film, 2016

Himura Hideo no Suiri - Japanese drama, 2016. There's a sequel coming up this fall.

Pornographer - Japanese drama, 2018. Adapted from a BL manga. Includes adult scenes.

Saka no Ue no Kumo - Japanese historical drama, 2009

Kasa wo Motanai Aritachi wa - Japanese mini-drama, 2016

Loosely related:

The Great Passage (Fune wo amu) - Japanese film, 2013. Main character is an editor working on a dictionary.   

Just adding:

Be Melodramatic - fl is drama script writer

Not sure if this counts but

Run On - fl is an interpreter/translator (usually movies)
