Day before Day 1

The middle child. The forgotten one.
The extra one in every friend group.
The talentless one. The pitiful one.
The oxygen-wasting soul.

Life is bright for everyone, but a bunch of fog for me.
Roses and butterflies for others, cockroaches for me.
Shiny for them, dirty and obscure for me.

How's life for a secondary character? Will I triumph and win?
Wait and you'll see...
