No offence intended, truly, if this is what works for you, and you're happy with it, go for it, but reading your examples I found them so boring and uninspiring that I now want to go read literally anything else but your stories. I always found those introductions tired, emotionless, entirely ephemeral 6th grade-level, SEO-driven writing. I am not arguing that there is a place perhaps for that kind of writing, but I would be careful about advising others to use it as a formula and derail their true style.
