Much like The Bond, Go Brother! focuses on a pair of siblings, which like your typical siblings fight and argue a lot. Only one day as a birthday wish, the sister wishes away her older brother and finds out she's now an only child like she's always wanted.
This, like The Bond, will pull at your heartstrings with the wholesome interactions to the huge realizations of how important true family is only once you've let it slip away.
I don't wanna spoil much but trust me, get a big box of tissue beforehand especially if like me you have a sibling, you'll want to go hug them real tight right after this.

10/10 recommend especially if you've just watched The Bond and need to fill in that void.
