Fu10 Day — Watching 18 31 Free

I can write an outstanding article—but I need to confirm what you mean by "fu10 day watching 18 31 free." I will assume you want a polished article interpreting that phrase as "Fu — 10-day watching period, ages 18–31, free access" (e.g., a cultural or film-watching program called "Fu" offering a free 10-day viewing window for 18–31-year-olds). I'll produce a compelling feature piece under that assumption. If this isn't right, tell me the correct meaning and I'll revise.
