The three of us are friends. 

Always have and always will.

There's the mother of our group, Soul who's calm, silent, but always present (and psychic). 

There's the child of our group, Lee Sungyeol, the only male that makes elementary kids look mature.

Then there's me, a little childish, but in a way different from the others.

We were always together.

We would always stand by each other.

...

Or so I thought.

But things change.

They always change.

Is there nothing infinite?
