"she had someone to run together with" and that's what it's all about, after all... the "I love you" as North Flight continues to surge ahead is so good, what a read lol
The way Bakushin and Flight run in this manga is incredibly explosive. I'd almost describe it as "Jet" like. Really sells the absolute speed both of them have reached.
In Umaland we don't say "will you marry me?"
we say "Its too short the mile we had to keep running together but its thanks to that one mile that I got to meet you."
Translating "daisuki" as "I love you" really sets a certain tone, hahaha. But seriously, I love how they manage to wrap race things up succinctly in 2-3 chapters without feeling shallow or ending too soon.
