Gaster was a funny fellow.

He made jokes frequently, and enjoyed puzzles very much. Gaster had the determination to never give up, even in hard times. This rung true even more when given tasks that some may find impossible, like finding cures for hundreds of diseases in just weeks.

Gaster was above-all valued for his smarts and charisma.

He was loved by many... Except the humans.

The humans despised Gaster.

But...

Isn't that the case with humans and things they don't understand?

Despite this, Gaster kept having a positive attitude.

Little did he know, his entire life would change when he met her...

Arial.

She was the bravest warrior ever known to monsters and humans alike.

The humans despised her as well.

They hated Arial for her charisma.

They hated Arial for her wit.

They hated Arial for her beauty.

The humans were jealous.

"Why should monsters, of all creatures, have the bravest warrior? What makes monsters so much more important than humans, God's most holy creation?" the humans would ask themselves.

Arial tended to brush these comments off, not allowing them to pierce the armor around her heart.

Gaster admired her deeply for this.

One day, Gaster began to court Arial.

After many years, and even more dates, Gaster proposed to her.

Arial, feeling deep emotions for Gaster aswell, accepted his proposal.

They felt that their happiness would never end.

But...

That's never the case, is it?
