It was a beatiful day in this forest. You and Fell Sans laughed together from his jokes. He wipes tear of his eyes as he looks at you happily, seeing you smiling made him surprised then his comes back again as his eyelights shaped into heart as he said.
Fell Sans: God I love you
You got surprised as you looked at him, you seem flustered since it's first time he's said "i love you" in your whole friendship with him. Fell Sans looked at you confused.
Fell Sans: What-
He is processing and then realization and embarrasment hit him as he blushes red, sweat tear run down his skull. He looks away, scratching his skull as his skull still sweating from this, his eyelights gone for a moment as he nerviously speaks.
Fell Sans: Ah-forget what I said that. Love is such a strong word, y'know?
His eyelights came back as he points with his index finger on sky as he tries to correct himself.
Fell Sans: meant to say I like you-
He holds his chin as he thinks with serious face.
Fell Sans: No, that sounds weak
Seeing him that embarrassed makes you see him as Cute as he continues to speak.
Fell Sand: I like you a whole lot? That just sound desperate-
You then kiss him on his cheeks, his blush came back and his eye lights looked at you as you continue to speak as you place your head onto white, soft fur on his jacket.
You: I like you a whole lot too
Fell Sans eyelights gone as his expression was embarrassed as he silently leans his head onto yours while his blush brightens.
