Frisk was quiet, sipping at her hot chocolate only to busy herself. Her fingers gripped the glass tight, her gaze cast down as she thought. She didn't notice Sans' little jump, though she glanced up at him shortly after Papyrus gave him his mug of hot cocoa.

She had to say something. The things left hanging between them were heavy and choked the air right out of the room. She could feel all the words she needed to say build in her chest, making it hard for her to breathe. She couldn't take this...She needed to get the words out. She glanced at Papyrus, silently hoping that he'd find the need to do something else.

As much as she hated leaving Papyrus out of the loop, she knew it was for the best. He didn't need or deserve such a heavy burden, especially when said burden was nothing but a ghost of past heartbreak and hostility that no longer existed. There was no point in dragging someone through something that, essentially, had never happened. So, when the taller skeleton declared he was going to take a shower, Frisk let out a mental breath of relief. 

Once he was gone, Frisk set her empty mug down. She didn't say a word and hardly moved, until she stood and gathered the two empty mugs. She placed them in the sink and sat back down. 

She was quiet for another moment. She bit at her bottom lip, tapped the counter, played with her hands...Anything that could distract her from talking to Sans. Eventually, the heaviness in her very being pushed her to open her mouth and draw in a deep breath.

"I think we need to talk, Sans," she softly said, still unable to look at him. "I know we've both wanted to leave it all alone, but that's not helping either of us anymore." She rubbed at her forehead, trying to ease her own stress. "I know it's hard, but--"

Frisk cut herself off, unsure where she was going. She swallowed and looked up at him with her forehead resting on her palm, elbow on the table. With her frazzled hair and rings under her eyes, she looked terrible.

"I need you to promise me something. I-I know promises aren't your thing, but...This is important."
