i won't let you leave me【Yandere!Sans x Reader】

You meet him...?

Interspecies relationships were still frowned upon, but usually, it only happened if it involved the soulmate bond which happened rarely enough in itself.

So it was a big surprise to suddenly have your soul burst out of your chest and fly across the street. A moment of déjà vu so strong that it made you stumble distracted you, but it disappeared once you noticed a car going full speed toward your mint colored soul.

Everything seemed to slow down and you dejectedly accepted your less than optimal death. Oh well.

But the impact never came. Realizing your eyes were squeezed shut from fear you opened them slowly, only to feel a pulse of warmth envelop your body. Ah. There was a floating car. The car that was going to hit 'you'.

Maybe you did die because a floating car doesn't seem right.

There was a moment of silence before you noticed a large skeleton with one eye (pupil?) shining a flaming...reddish blue, the same color that covered the car. For a second the skeleton looked so panicked you thought something was wrong, but his...eye(?) turned to you, and you felt everything click into place.

He was your soulmate. You knew.

Despite being an actual skeleton, his face was very animated. His gaze was on your soul, then on you once again.

You expected him to just drop the car, but you were pretty surprised when he lifted it-arm following but gaze still on you-and smashing it into the ground while it crushed anyone inside.

Oh.

You glanced sideways to notice a faint outline of a heart start to come from the car before it disappeared. You blinked. You thought maybe you saw the skeleton there for a split second. But when you turned back to where you thought he was he indeed was still there.

"...heh..."

He didn't look right. You weren't scared, per say, just, uh-shocked? He kind of just killed someone, and instead of showing remorse, the widest smile was on his face. That really didn't look natural.

Did you almost dying make him react instinctively or something? That seemed reasonable, but he really didn't need to smoosh the car. Or kill the person inside.

Hm.

Where was everyone else? Wasn't there people here before?

You peered back toward the skeleton, who was cupping your soul close to his face. Did his eye lights (you decided to call them) just flicker into hearts for a second? Was that just you? You scurried over, feeling intimidated by his stature.

You had to strain your neck to look up. "Hey. Um...thanks for, uh...saving me back there, I owe you one." Your voice wavered slightly, but you tried to keep it steady. He didn't mean to kill the man. It was an accident from panic.

He's too happy for it to be an accident, you thought briefly.

He looked down at you before crouching so you were eye level, his unsettling smile falling into a more relaxed grin. You saw a brief flicker of numbers in his eyes before they disappeared. Something about EXP...? It looked to be ascending numbers...you really couldn't make it out before it was gone.

You had a feeling it was important.

He kept staring at you before you saw the blue (and kind of red) magic coat his hands and envelop your soul. It felt nice, warm, and comforting. You feel safe and protected. What was he doing to make you feel so relaxed and happy? This seemed especially intimate.
