Laying on the ground was a skeleton too lazy to get up, and sitting on the couch was another skeleton, this one to sad to show his face.
And entering the room was a fish-like monster with legs. She had learned about her friend's depression only today and was very worried. For this reason, she had stayed in Sans and Papyrus' house. You wouldn't expect anything less from a hero.
"Woah, woah woah! What's going on?" Undyne asked, looking back and forth between the brothers.
"Papyrus is angry about nothing." Sans told her matter-of-factly.
Undyne cocked her head. "He looks sad to me."
Sans paused to think, still on the carpeted floor. "Well, he is. But he's angry too."
"Papyrus, what are you angry about?"
Oh. She was talking to Papyrus now. Papyrus open his mouth to speak, but he found himself having trouble doing so. But somehow, he managed. Shaking with every breath, Papyrus ashamedly filled her in. "I-I d-didn't like th-the therpaist... H-he w-was mean... well, a-actuall-ly, he w-wasn't, b-but he hurt my feelings and- w-wow, this is h-hard to explain..." He took a moment to gather his thoughts. When he started talking again, he was going much faster."I d-don't know why I did what I did, b-but I hate it and now Sans hates me and-"
Sans sat straight up. "Woah, woah! What do you mean, I hate you?!"
Papyrus turned to look at his brother. With so many tears in his eyes, it was hard to see, but from what he could tell, his brother wasn't frustrated anymore. Not at all.
"W-well, you're mad at me..." Papyrus stated.
Sans seemed to be getting more and more concerned. "Yes, but that doesn't mean I hate you! Why would that mean I hate you?" he questioned.
For the third time that day, Papyrus said, "I don't know. I don't know anything I guess."
As Undyne stood awkwardly, Sans lifted himself up off the ground.
"I'm sorry, Papyrus."
The basic-looking guy seemed surprised at Sans' words." "Y-you didn't do anything!" he exclaimed.
Sans was walking over to him. "I made you cry," he debated.
The taller of the two was now back to making eye contact. "Well, yeah, but I made myself mad!"
Sans put his arms around Papyrus. "Well yeah, but you're sorry too, aren't you?"
Papyrus was surprised by the gesture, but hugged Sans back. "Yes, but what does that have to do with anything?"
"It means we're both sorry, and what we both have done is forgiven."
Papyrus was barely understanding. "...Forgiven?"
"Forgiven," Sans repeated, "You forgive me, right?"
"R-right," Papyrus was silent for a bit. "Does... does that mean everything's okay?"
"It does."
Once again, Papyrus smiled. Sans smiled too.
"So, do you feel like going to therapy tomorrow?" his voice sounded soft.
Papyrus said no, and Sans told him that was okay. He just wouldn't go, then.
Undyne was grinning wide, in a super goofy manner. "I don't know what just happened," she announced, "but I love it!"
Papyrus jumped off the couch. "As soon as I wipe my eyes we can do something fun!" He was actually happy.
Fast forward a couple minutes, and the three monsters were sitting at a table, playing Monopoly. Papyrus had just won for the 3rd time. Whether they were letting him win or he was just good at the game he didn't know, but either way he felt really proud of himself. Sans joked that he could become "undepressed" again if they play Monopoly every single day.
"Okay, we should play something else," Undyne said, obviously bored.
"We could play Tic-Tac-Toe," Papyrus suggested.
"That's a two person game." Undyne pointed out.
"Oh yeah. Then we could play indoor snowball fight!" he said excitedly.
Undyne had never heard of that. "Indoor snowball fi-"
Undyne was interrupted by a paper ball hitting her right in the face.
Undyne was annoyed, however, considering Papyrus' diagnosis, he couldn't have been happier. So Undyne threw the makeshift snowball back at him. Papyrus effortlessly caught it.
Sans was having a great time not needing to participate in the game, but then he noticed the ball of paper flying towards him, which he dodged. The ball traveled across the room, and landed somewhere. "Whoops, I think it's lost," the pudgier guy said.
"Too bad I don't have more of them," Papyrus said, before proceeding to pelt the others with what was, in fact, more.
The balls were thrown back and forth for at least 5 minutes before all of them either got lost or were thrown in the trash can.
Despite Papyrus' early start, Undyne won the fight, and she seemed very proud. Though Papyrus didn't win, he had a good time, and that's all he felt mattered, the same with Sans.
The sun set and Papyrus came to a stunning realization: it had been a good day.
