My idea of a life coaching business

I am a huge Chinese drama and Arts fan who is focused on self-development.
I have been wanting to create a platform to host Chinese drama fans around the world – charge a fee for entering the platform and monthly fees for maintaining the membership and I want people to share their passion about the topics but most importantly use the inspirations of what we watch to better ourselves consistently.
I also want to hire a life coach for the platform to do life coaching on various topics. The life coaches should be drama fans themselves and who also focus on self-development.
I know I am at the ideation stage but I think there’s an opportunity there. Can you please give me some feedback on this idea and niche?
Do you think I can charge money for it?
