"Congratulations Sans! you found love"
"........Love......?"

Sans wondering... what actually love that Paps talking about before, he can't throw it from his mind even after Paps finally sleep on the sofa. He really want to ask Frisk...but every time he open his mouth to ask, his soul will jump and that weird feeling will come back, make Sans shut his mouth instantly. Frisk finally come back from upstairs smiling silently to his bro who snoring loudly.

"Sans.. can you help me bring Paps to your room?"

With nods he let his left eye burn with blue magic again, he lift Paps like nothing in the air then gently bring him to his room, placing him on his bed. After put Paps there Frisk prise him with smile and rub his skull gently make him lean more to her touch.

"Welp.. i guess today i will take the sofa"
"Who said you will sleep on the sofa tonight? really it's not comfortable"
"Huh.? so... where i can sleep then?"
"With me of course"

Sans face burning from embarrassment when he hear that and he 100% sure he got a mini heart attack that time. Frisk notice this and smirk.

"Woah... Sans you are blue-sing"
"I'm not!!"

Sans cover himself and zip his jacket until his entry face buried inside of it. Frisk chuckle a bit but stopped when she saw a glowing blue that appear faintly inside his grey clothes and jacket. It's glow must be very strong that can still showing its glow even after get covered by two thick fabrics. Being a curious human, Frisk touch the area where the faint glow appear and that was his chest, made Sans yelp a bit.

"F-frisk what are you doing?"
"Your chest glowing... it's pretty"

Sans slowly peek from his hoodie, looking at Frisk who still staring at his glowing chest in awe. Why she so attached to his soul so much? is that's really pretty for her?
With snap of his finger he let out his soul, a blue glowing heart floating near Frisk who staring at it with eyes filled with joy and happiness. Sans know that if he let out his soul, that's means he is in great danger, because if someone stab it he will die instantly... but really... seeing Frisk like that... all the danger is worth it.

"Please... keep it... but... be careful, uh... that my life... and ... uh..."

Frisk taken back by his words....
'this is his life... is not this is super important? why he give it to me?'
Frisk hold it close to her chest.. feeling its vibrating happily because her touch, she stare at Sans who still fidgeting in his spot. His soul tied itself on her neck, turning to be a beautiful blue heart shape necklace. She can't take this very important present from him if she doesn't give something back.

"Hei Sans.."
"Yeah...?"
"Do you ever trying to pull someone else heart?"
"Ah... never think about that, why do you ask?"
"Try pull mine then"
"Ok- eh... what?"
"Just try okay"

Sans looking very unsure about it but nods anyway, he focusing to her glowing red heart and pull it out. Frisk feel dizzy for a moment when he pull it, but now she can see her own heart.... a red heart that shine gently. Frisk smile and send her heart to the Sans direction, force him to hold it close in his arms, making him stare at her with questioning stare.

"Treat it kindly okay..."

Her heart tied itself to be a necklace as well, and Sans can feel the warmth that her soul send to him, he wonder, what he soul send to her? Frisk snapping him from his daydream and pull him to her bedroom.

"Gez.. what a long day... let's just sleep kay"

Frisk yawn and throw herself to the bed, Sans yelp when she pull him with her and then hug him close.

"F-frisk?"
"Hm...."

Frisk already fast a sleep with small smile on her face... Sans really want to brust in happiness but he afraid he will wake her up, so with trembling and shaking hands, he hug her back enjoying the warmth and affection she give to him, then he smile.

"This gona be a long night"
