Absolutely incredible song Commission from  teacorgi
based on the Digimon Adventure intro Butter-Fly
Here are my favorite versions of it:

A couple of versions stuck together, the classic, a 10 year old video

The first time I actually heard the original intro, which prompted a whole rewatch of the series with subs! (which if you've never done, you 100% should)

Seriously huge props to they absolutely nailed the feelings this song gives me, I treasure this art so much! Everyone should be commissioning them, they are incredible!!!
