I have four friends:

Sam

He’s always in a good mood

He excludes the thought of something or someone knocking him down

He is always optimistic

And he just can’t stop smiling about the things that make me “happy.”

Alice

She has Sam’s back

She wakes him out of complacency before something or something hurts him

She’s his forceful conscience 
She looks out for him, for as much as it is allowed

Brody

He’s always in despair by the hurtful truth, or the insecurities that he is too weak to brush off
Brody is broken because he doesn’t know how to handle the worse that has happened

He stays in bed for the whole day and night

He has these scars on his arms and bags under his eyes

Rebecca

She works as hard as he can to bring Brody back up

She is closely related to Alice because she also takes care of Sam after he actually gets hurt

She repeats optimistic songs, movies, and quotes

She looks in every direction and dimension to help Sam and Brody.
