Fan of Hong Kong star

About

The protagonist is a woman (Hiroko Yakushimaru) who is a sales manager at the Japanese branch of a famous French shoe brand. The protagonist is obsessed with a Hong Kong singer called Eakin Cheng and frequently goes to Hong Kong. However, she herself has an ambition to change the company's marketing policy (and if she can't change it, she will launch a new brand herself), so she goes to Hong Kong to plan this and that. However, this comes to light, and as it goes against the wishes of the head office, a feud is brewing between the two.
