Moon and Sun

Sophia is a happy person. She sees the good in others. She always has a smile on her face. She's a bit weird, but that's who she is. People call her the Sun because she brightens people's days.
Mike is a quiet person. He wants to always be alone. He's depressed and always stays in his dark room doing who knows what. People say his soul is dark. He's called the Moon.
They're complete opposites.
What happens when they start hanging out.
There's always light in darkness.
There's always darkness in light.
That's why they need each other.
