Have I Become the Supporting Actor in a Love Show?

It's a classic light novel. I still don't know how much more work the author wants to add to it, but it's still very interesting so far. Recommend

[Background of the work]: Modern overhead [Protagonist Attributes]: System + Entertainment Entrepreneurship Emotional Line: Multiple heroines [Main Plot]: Lin Shan, a social animal, travels through time and becomes Ikegami Sugi, an 18-year-old college student. His identity is the "badass male supporting actor" in the original love story (standard tall, rich and handsome but responsible for being a stepping stone for the male protagonist). He originally wanted to lie down and enjoy the cash-recharge life, but he was bound to the "popularity system"-if the series he is in is not popular enough in the real world, the world will usher in the end. In order to avoid "being cut in half", Ikegami decided to take over the screenwriter's pen. He used the memories of his past life to establish the "Ultraline Club" and "Ultraline Studio" on campus. By releasing popular songs and MVs such as "Sakura Sakura Wants to See You", "Ultramarine", and "Pure Land", he wildly harvested the popularity of real-life audiences and changed the originally stomach-ache love story into a "career flow". There are many female protagonists who clearly want to be in the harem, and the female protagonist types include royal sisters, lolita, sanwu, etc. It is a light entrepreneurial novel in the context of Rixin campus.
