[Betting on U] has a meaning of [having extreme confidence in someone]. This song explains how he wanted her to show his true feelings to him, an answer to a question: “Will you accept me if I show you my true self?”, which is the main theme of JuisMeru itself.

Black and white even if we settle it Today as well, the world remains ambiguous
(Without taking side) drifting along with each other (Things that don't even matter) Desiring
Even if someone bows out first, the balance goes crazy Beyond our control, like a seesaw
=
It’s like they have to be together in order for them to be balanced, like a seesaw. Like an anchor to each other, maybe?
The bargaining is Feel bad? Alright
