You were on another fresh run after you RESET your last one, since Sans said he'd finally take you on a date. So you met up with him once again, and it began. You guys were straying off from the main story, but it didn't matter.

At first, it went sort of well, albeit awkward. He took you to Grillby's, then a secret spot in Waterfall. Until he brought you to MTT Resort. That's when it escalated, and soon enough you found yourself (or rather, 'whoever's body you were controlling this time', as per Sans' words) telekinetically being thrown against the wall by Sans in anger. Although his rage quickly turned to sadness as he dropped you.

"I... I can't do this."

He himself dropped down as well, sitting on the shiny floor as tears flowed out from his eye sockets.

"I dont want to do this. I dont actually want to hurt you. I'm just so sick of being down here. There's nothing left to do. I thought, maybe, if I just focused on the little things... Family, friends, laughter... That it would eventually subside. But... It doesnt. Ive lived and died here so many times. Ive seen hell and heaven, theres nothing left for me to do. Its like im immortal, but i still die."

"You dont make it better. You've just made it worse. For the record, I gave up hope of going to the surface long before you showed up. But then, to finally see it... Only to wake up and find it was all a dream...? It's like torture."

"I dont know if im real anymore. I dont know if this is real anymore. Is ANYTHING real?"

Sans paused for a moment.

"It sure doesnt feel like it. I dont even know if you're real."

He just continued speaking, about how there was nothing else for him to do, how he doesn't know if anything is real anymore as his smiling grin never faltered but became alot weaker and strained. He closed his eye sockets, tears still running down.

"Why? Why do you come back here? What is so much better here that you'd rather live in the same loop over and over again, just to see us? I dont understand. I cant understand."

Sans continued to speak about it all before opening his eye to look at you and letting out a weary chuckle, wiping his continuous tears with his blue jacket sleeve. But that's when he heard you say 'sorry'. And then he let out another.

"Heh.... 'm sorry too. For dragging you into my own mess like this. You...probably have your reasonings for what you do. Though it doesnt feel good, being stuck here like this. Seeing you come through here all the time for fun. No matter what you do, It always makes me angry. But i bet you never noticed, huh? Or maybe you did."

His gaze wandered off to the side as he looked down at the ground.

"I don't... I don't really like sayin' how I actually feel. I dont wanna bother people. Everybody's got their stuff to worry 'bout, they dont need to add me to that list. So... I learned the timeline pretty quick, and just said the same thing every time. I didnt want to let people know i noticed the changes."
