Innocence at it's worst ? X'D ( I mean High school can be a trip. And usually people that enter that level usually their innocence is idk not there anymore? ) ( pfft, don't listen to me x'D freaking art block. )
Uhm, how about. joie de vivre ( meaning: like being carefree or as well as enjoyment of living which can be a reference to maybe succeeding into making it to high school. )

My heart is weak, Only idiots reach up the sky, Let's be weird together, You're always in my thoughts (like an idiot who can't stop dancing), Miracle of being a fool (this title is taken after a movie with Cha Taehyun)
I know they're crappy, I literally came up with them in two minutes, but maybe it'll give you some inspiration

i was about to ask "which pairing" but then i saw the tag, haha.~

right now the only thing i can come up with is "idiocy" but that doesn't sound like a good title. ;;
