Sans:

Count me in unannounced
Drag our friends on the tiles
I just follow your trial
You can't just follow my smile
All your sins are aligned
With this mood of mine
Cutting me to the bone
Nothing left to leave behind
You outta reset right now,
Just like it never happened
I didn't come for a fight,
But I will fight till the end
And this one might be your battle
Might not turn out okay
I know you think you can kill me,
But you've already lost the
GaaaaAAAA
AAAAAA
AAAAAA
AAAAAA
AAAAAA
AAAAAA
AAAAAA
AAAAME

Sans:

And I LOVE the way you "hurt" me
It's DETERMINATION
Oh oh oh oh oh oh, yeah

Both:

Oh oh oh oh oh oh, yeah

I LOVE the way
I LOVE the way
I LOVE the way you keep on trying
I LOVE the way
I LOVE the way
I LOVE the way you keep on dying

Chara:

I'm gonna break you to pieces
Just like you were your brother

Sans:

Gonna kill you again
Just like you killed your own mother

Chara:

You're a fool with no past
Say goodbye to your future

Sans:

Pay the fee,
Do it, kid

Both:

I'm talking no Inflation

Too many stab wounds
And not enough items
Too much time in the halls
I feel my sins start to crawl

Chara:

Too many FREAKS
Not enough blood in the game

Sans:

You know I'd give your LOVE
A F-F-Four letter name

Both:

Eh eh eh eh eh
Eh eh eh eh eh
Eh eh eh eh eh
Eh eh eh eh eh
Eh eh eh eh eh
Eh eh eh eh eh
Eh eh eh eh eh
Eh eh eh eh eh

Sans:

And I LOVE the way you "hurt" me
It's DETERMINATION
Oh oh oh oh oh oh, yeah

Both:

Oh oh oh oh oh oh, yeah

I LOVE the way
I LOVE the way
I LOVE the way you keep on trying
I LOVE the way
I LOVE the way
I LOVE the way you keep on dying

Chara:

Kill me again
Again and again
But I come back knowing so much more
Learning all your tricks
It'll make you sick
Cause the truth is Sans
I'll make you QUIT
Hehehe

Sans:

Try to stay Frisk
Please just stay Frisk
You're still good, kid
Admit to this
Don't fight anymore
It's just a snore
One more step,
And I'll make it war

Chara:

And I still LOVE the way I "hurt" you

Sans:

Hahahahaha

It's DETERMINATION
Oh oh oh oh oh oh, yeah

Both:

Oh oh oh oh oh oh, yeah

I LOVE the way
I LOVE the way
I LOVE the way you keep on trying
I LOVE the way
(I LOVE the way)
I LOVE the way
(I LOVE the way)
I LOVE the way you keep on dying
