Chara didn't have an end in sight. They just needed to get away from there. From that house. So they ran. And they kept running. Even when their lungs burned and their vision began to blur, they continued to run.
"Nuisance!"
"Pest!"
"Waste of space!"
"Who even needs you?"
"Stop crying like a baby!"
"Freak."
"Trouble maker."
"Ungrateful brat."
"Monster."
"NO!" Chara screamed. They stopped running as tears fell down their cheeks and they slammed their fists into the ground. They looked down and saw that they were in a field of buttercups. Their hands were shaking as they sobbed out loud, falling to their knees.
They sat on their hands and knees for they didn't even know how long, sobbing and pounding the flowers. They looked down at the flowers and choked back another sob.
They thought about the monsters that had taken them in. Smiling Asriel, always timid but excited. Kind, generous Toriel. And mighty, strong Asgore. Although, he wasn't so strong anymore.
How could they have been so stupid?! They knew how to read just fine! They should have seen the space and known what to do! They might have killed Asgore…
Chara looked down at the buttercups underneath them and picked one. They examined the flower before closing their eyes. They began to bring the flower to their mouth and-
"Chara?"
Chara opened their eyes at the familiar voice, but still held the flower. Asriel came running up to them as the human wiped their eyes with their sleeve.
"I thought I'd find you here," Asriel said as he looked around the edge of the Ruins. He held out a paw and said, "Mom and Dad are concerned for you."
Chara turned away from Asriel and said coldly, "Leave me alone."
"Chara, it's alright. Mom said that she overreacted a bit. Come on."
Chara still wouldn't face him and Asriel sighed. "We really messed up, didn't we?" he asked.
"'We'?" Chara asked defensively, still not facing Asriel. "There is no 'we'. I was the one who said to add buttercups. I was the one who said that we should add flowers from the garden. I was the one who killed Asgore!"
They yelled the last sentence as they pounced the flowers beneath them again. Their breath was shaky as they tried not to cry. They said in a whisper so quiet it was almost inaudible, "I killed Asgore."
"Chara, you weren't the only one responsible," Asriel insisted. "We're both at fault here. It's both of our fault. But Mom said that Dad won't die! He didn't eat nearly enough for that to happen! He's just gonna be sick and weak for a bit."
At these words, Chara laughed a bit and asked, "Really?"
"Yes, really! Now please come home with me. Mom gets nervous when we come to the Ruins without her, especially the edge."
Chara laughed again as they looked up at the hole that they had fallen through. "Why do you guys keep me?" they asked, their voice soft.
Asriel tilted his head to the side and asked, "What do you mean?"
"Why do you guys even let me stay here with you? I'm nothing but a pest. A nuisance. A thing that nobody asked for."
"Chara, that's not true! We love you! We love having you with us!"
"But why? What did I do to deserve happiness? To deserve mercy?"
"Everyone deserves to be happy Chara. Everyone deserves kindness. To be loved and cared for. To be wanted. You deserve those things Chara."
Chara laughed once again and shook their head. "I don't understand," they said. "I don't understand. I just don't understand."
They got up off the ground without Asriel's help and dropped the buttercup in their hand. "Let's head home," they said.
