The three heirs to the throne stand in the throne room when he enters.

Ebott Kingdom has suffered for a long time. King Asgore, heartbroken when his wife left him, had created a kingdom of tyranny. Every year, Snowdon welcomed people from Ebott who were starving and dying.

The king before Sans, Gaster, his and his brother's father, believed in appeasement. So, the kingdom stood by. They allowed Ebott's people to enter, but nothing else.

Sans decided to take action. He might've been a lazy prince, but he wouldn't be a lazy king.

Prince Asriel, the only actual birth child, stared at the floor. He might've been crying- it was hard to tell. Princess Chara, the oldest of the twins, stared at him with an odd and creepy grin. There was a light in her eyes that suggested that the knives should be locked away.

Princess Frisk stared at him as well. Her expression was one of calm. But her amber eyes showed her emotion: a mix of gratitude, anger, and confusion. That was easy to understand - she had loved her adopted father, but the bruise on her arm showed the stories of abuse were true.

Sans feels his SOUL beat excitedly as he stared at her. He has heard stories of her sweetness and kindness from her subjects, one particularly good artist painting a portrait for him. He keeps it tucked under his clothes, next to his SOUL.

He makes Asriel the new king.

-_-

Sans sees Frisk again and again. Diplomacy means he has to help rebuild Ebott, according to the new peace treaty Frisk helped write. Which means he gets to see her.

He works on charming her, promising to himself to back away if she gets upset with the skeleton that put her father in the dungeons. Thankfully, she never gets upset or seems uncomfortable.

Two years after the invasion, they meet at a ball. He's hosting it, thanking for the years of peace.

He leads her away from the ballroom. "Where are we going?" Frisk whispers.

Sans doesn't answer, leading her into the treasury. There is no lighting, so he holds a candle. The hairclip, a ancient artifact from the long extinct race of shapeshifters, sits on a pillow. It is carefully crafted, the shapeshifters being seers, and looks real.

"For you."

She stares at the hairclip in shock. "I-I can't accept this."

"Please, do." Sans grips her hands. "Accept this, and me." He kissed her cheek. "Marry me."

She stares at him. "Yes."

The candle goes out when they kiss.

-_-

A few months later, Sans talks to Asriel.

They receive his blessing.

Their engagement is announced the next day, the two holding hands on a balcony as their mixed people cheer.
