Here’s the most likely free option for Pre-Bo / PRE-BO episode 1 with English subtitles: a Dailymotion upload titled “Pro Bono Episode 1 | English Sub” from StoryHaven, which appears to be the closest match to what you’re looking for

. There’s also a YouTube result labeled “PRE-BO The Beginning | BL Movie | Free Version” , but it looks like a movie/free version rather than episode 1 specifically

Where to watch

  • Dailymotion: The clearest “Episode 1 | English Sub” match in the results is on Dailymotion
  • YouTube: A free version titled PRE-BO The Beginning is available, but it may not be the exact episode you want.
  • Official-style BL library options: GagaOOLala has a free section and also carries BL titles legally, though availability depends on region.

What to watch out for

  • Upload titles can be inconsistent, so “Pro Bono” may be the same series or a mislabeled upload related to PRE-BO.
  • Free uploads may be unofficial or temporary, so quality and subtitle accuracy can vary.
  • If you want the safest route, check whether the title appears in a legal platform’s catalog before relying on a random upload.

Best bet

If you want the fastest free watch, start with the Dailymotion result first. If that doesn’t match the exact series, try the YouTube free version next.

TL;DR: The best free lead I found for Episode 1 with English subs is the Dailymotion upload, while YouTube has a free PRE-BO version that may be the movie/spin-off rather than the exact episode.
