At the end of chapter 1, watch the whole cutscene and don't skip it.
Skipping it, for whatever reason, means the achievement won't pop

I got stuck on this playing the game twice and not getting it.
Third time I played it however, I let the cutscene run and I got it.

If this isn't what pops the achievement then I'm very sorry and I hope you get it soon but that is what fixed it for me personally

I hope this guide helped you, please like it if this helped you out :)
