Chara smile faulted as Sans opened up to her. She felt guilty that she took part in his added pain by her actions underground. Worst thing was, even if she knew any of this back then, she wouldn't have cared, she would have used this against him and take enjoyment in his pain. Then she realized that this was the reason he didn't want to date or anything, he didn't plan on staying, this hurt, and Chara knew it was for a selfish reason. She took in a deep breath, slipping her hand from his. "I'm sorry, I didn't know that...if I had a father like yours, I would feel the same. Your perfect life was taken. I know this timeline is shit, trust me. If I knew there was a timeline out there were I..." she paused for a moment, thinking that maybe there was a place where she was happy, had a family that didn't hate her, or that she was never born. "Maybe...I should go. Do..do you want me to leave?" This was the last thing she wanted to do, but her being there was taking him from his work, because he was always having to pretty much babysit her because she was so unstable. Slowly she stood, just the thought of leaving broke her heart. Walking over to him she felt to her knees beside him, wrapping her arms around his waist, Saying nothing else, just holding him tightly with her head on his chest, wanting to cry, but she didn't want to start the day off in tears.
