"Is there anything you do like, Chara?" Asriel was exasperated. The monster had been trying to find something for you to eat in the fridge, but you couldn't bring yourself to eat any of it. After the whole thing with that stuff that was literally made of spiders, you didn't trust any of the food you hadn't had before. You refused to go through that again, yet everything supposedly edible was new and strange. And Toriel and Asgore, or Mom and Dad (you thought you'd never get used to that) weren't going to let you survive off of pie forever.
You shook your head firmly. You weren't that hungry anyway. Asriel frowned. "But you haven't eaten anything since yesterday! If you don't, y-you'll…" You could see tears welling up again. You rolled your eyes. He was such a crybaby sometimes.
"Fine," you muttered. "I'll look. But I'm not promising anything." You made sure to emphasize that last part before stepping forward to look into the fridge, the cold air that flowed out striking you in the face. You scanned for anything you might like to eat, but the most appealing thing you saw was a weird-looking sausage (you hoped) that had weird-looking cat ears at the end. Needless to say, you didn't want to touch it.
You were about to simply close the door and be done with this, when you spotted something at the back of the top shelf. It was something you never thought you'd see: a rectangular bar covered in a purple and brown wrapper. You reached up immediately and grabbed it without a second thought.
"Hey, you found something!" Asriel said. "Wait, that's not-"
You cut him off as you unwrapped the chocolate bar with intense fervor. You had never been able to have this treat in your old life. Just seeing it brought a grin to your face. You didn't hesitate before taking a large bite of the bar. The flavor exploded in your mouth. It was so sweet, yet not so much that it was sickening. It felt as if it had been an eternity since you were allowed to eat it.
Asriel attempted to stop you, saying "Chocolate isn't really food!" but you were finished with the treat in seconds. You found it hard to suppress the urge to eat what you were given in seconds. But now, you could tell the area around your mouth was coated in the sweet substance. You didn't care, but Asriel looked just a bit miffed.
"Chara! Mom said you need to stop eating so many sweets!"
You shrugged, licking around your lips. "It's better."
Your adoptive brother sighed, knowing you weren't going to change your mind any time soon. Even in the short time you'd known each other, he already knew that there was no stopping you once an idea got in your head. He always said you were too determined.
As the two of you left the kitchen, you heard someone else enter. It was probably Toriel, since her footsteps weren't nearly as loud as Asgore's. You could hear her opening the fridge, and the startled gasp as she realized something was missing. Just as you shut your bedroom door, you heard her say, "Asgore, did you eat my chocolate?" You giggled and turned away.
"You know you still need to eat something substantial, right?" Asriel asked. He had retreated to his bed, and his legs were dangling off the side of it. Similarly, you hopped onto yours and shrugged.
"So what?"
Asriel started to kick his legs outward a bit. "Well, you don't want to get unhealthy or something right? And it's not like you can't eat anything down here." You ignored him and picked up a toy you had left on the bed. The doll was simple, but you suspected it was magic or something because no matter what you did, you could never seem to break it. At first, you had only accidentally stepped on it, and thought it had broken. Then, you had set yourself to trying to break it just to see its limits. Progress was slow.
"Wow, you're pretty aggressive with that thing, aren't you?" You hid your surprise. Asriel had managed to come up next to you without noticing. Why did he have to be so clingy? Just because you were technically siblings now didn't mean he had to be around you all of the time. Part of you wanted to just read a book like Toriel kept suggesting just to keep him out of your hair. "Are you trying to break it or something?" You nodded. "Oh…. I don't think you can. Mom said she got it enchanted so it would be almost impossible to break it."
You ignored that as you yanked as hard as you could on one of the doll's arms. You were determined to break this thing, no matter how long it took. Why, you weren't too sure.
"You know, Chara, you're kind of funny sometimes." You turned slightly to glare at Asriel. Were all monsters this annoying? He quickly recoiled. "I-I mean in a good way. Like, you're interesting." That softened your expression, if only for a moment.
"Interesting…?"
He nodded, his ears flopping a bit as he did so. The smile on his face was larger than life. "Yeah, you're cool. And not just because you're a human either. I really like having you around." You could feel blood rushing to your cheeks. You turned away, hopefully before he could see your blush.
That was probably the nicest thing anyone had ever said to you.
You put the doll down and stood up from the bed. "Maybe I'll give the food another shot." You could practically feel Asriel's smile bearing down on you.
