Ah, friendship anniversary. Such an amazing time for friends to get together and have fun while remembering all their great times together.
"Oh, remember the time you dared me to kiss Mel and I nearly puked?!" Sans laughed.
"Or the time you fucking kissed me for no reason?!" Olive yelled.
"Shut up! That's when I had a crush on you and didn't know you were homosexual." Sans blushed in embarrassment.
"Remember when I finally grew the balls to kiss Sans?" Frisk giggled.
Sans just blushed an smiled at her.
"What about the time Mettaton beat Sans in a dance battle?!" Papyrus yelled enthusiastically.
"Yeah yeah whatever.."
"Hey, I wanted to show these to you guys!" Olive said pulling out a drawing. It was all of them playing uno, and it the middle it said 'My friends, My family.'
"Olive, that's so sweet!" Chara said. She never really was that happy.
"But this is mine, I made you all different ones to put on each of our rooms. You can choose which one you want."
Everyone chose which one they wanted. Mel chose the one where she was sitting on the couch with a tired expression and everyone was around her yelling and laughing. Sans chose the one where is was him and Olive dancing together and there was a caption that was pointing to Olive that said, 'She's gay, don't ship us.' Papyrus chose the one where everyone was happily eating his spaghetti. Chara chose the one where she was threatening everyone. Frisk chose the one where they were all singing some sort of song, but they were all drunk.
After some time, they were all just sitting around and talking.
"Let's go somewhere. How about the cave over by the waterfall that Pap and Undyne found?" Mel said.
"Cool, let's do it." Said Chara.
And so they went, Papyrus leading the way.
They got there, and Olive grabbed a bunch of branches and started to construct furniture to put in.
"Heh, that pretty cool, kiddo."
"Oh, thanks. It's supposed to be a Chair. I'm probably gonna get some fabric and stuffing and make pillows so it's more comfy." Olive said.
"Huh.. cool."
Olive continued building as the others talked and Sans watched oddly thoughtfully. After the chairs were done, Olive rolled up her sleeves and headed out to get some more wood. She seemed off to Sans, however. Sans followed her, and tried to talk to her. She responded passively, with only 'Yep,' or 'Uh-Huh.'
"You ok? You only smiled once today when you gave out the pictures." Sans asked Olive.
"Yeah, I'm fine."
"No you're not."
"Then what was the point of asking?" Olive said and turned to Sans, her iris was black. Sans felt awful, like he did something wrong.
"..Sorry. I won't get in your space like that again."
Olive did not respond. She collected wood and kept building. Sans watched her. While she was building he noticed there were somewhat new cuts in her arms.
Olive noticed Sans see them and quickly rolled down her sleeves.
After that day, Olive became more and more distant from the group. After a little while, Olive went missing. Sans was ruined.
He looked for her constantly, but no luck. Not even a trace.
He went to the cave by the waterfall and the cave had walls and a door. Sans had hope, and sprinted over, warm tears streaming down his face. Surely Olive was in there, right? Sans opened the door and saw Olive! He ran over to hug her. She looked healthy, and perfect. She looked at Sans and smiled. Sans hugged her, but fell into the chair that she was sitting in. The chair was empty.
"No.. no... nononono... you can't be gone, you aren't gone..." Sans bursted in tears. He noticed a note on the table.
Hi, Sans!
I know you are the one that found my note first, you care about me the more than anyone does. I wanted to tell you, I'm alive. I'm not dead. I am just not there. Please don't look for me, it's not worth it. Do as I say to stay safe. Please stay yourself and be happy, you are better without me. Don't tell the others about this, and keep this place to yourself. Come here when you feel negatively.
You are like a brother to me, and I love you.
~Olivia, Your sister
Sans read, bursting into more sobbing.
"Fine, Olivia. I'll do as you wish. I love you too." Sans said, DETERMINATION shining in his tears.
