You entered Grillby's bar to check up on Sans... But you notice that Grillby added something to Sans's wine... as he drinked more wine... Sans's face gets redder and redder as Sans's SOUL beats faster and harder in his own chest... His Soul's light was illuminating through his clothes, revealing it's state and how it moves... as he looks at you in drunken love? As he spoke in deep and raspy voice...

Sans: M-my heart is working so much... so hard... Oh?!? H-heya, kid...
