"IDK I'm bad at summaries/tags/titles, hope it's not terrible. :/"
Yeah quick question: if you, the author, the person who wrote the thing from start to finish using exactly the tropes you wanted, don't think it's good...

Confidence is actually a lot easier to fake than you'd expect (source: said "fuck it, I'm pretending to be confident from now on" a year ago, now I'm actually confident).
But faking confidence over text, where people can't hear the shake in your voice or see the widening of your eyes? Elementary! All it takes is "not putting yourself down" et voila!
