After Traumatizing events of Underverse war was over and Classic Sans has gained his Full Soul but...

7 days later... you were walking around Waterfall seeing beautiful light and crystals, and darkness making atmosphere... Suddenly Classic Sans teleported infront of you as he suddenly cornered you against wall... You could see his clothes shining from blue light of Waterfall crystals... You could hear Steady beats... So stable rhythm of His Soul in his Ribcage, as you could see that his clothes quite dark from darkness but blue light from rain of Waterfall makes it beautiful... as he looks at you as his white eyelights shines in the dark... His Permament Grin widens slightly... His hands is still in his jacket pocket... As he spoke in mischievous tone...

Sans: It's beautiful here isn't it? Heh, kid... Heh... Toriel said to check up on you... Since Monster-kind was freed from Underground... Y'know... Monster-kind and Human-kind got along pretty well... But I can't help but...

He suddenly pins you against him, not the wall... As he looks at you mischievously.

Sans: After that events... I thought... all these traumatized events even before monster-kind was freed... I remember in Waterfall where you get attacked by Undyne many times... Good ol' days but I thought... Your deaths were painful for you... I felt like... You need some type of affection... Now... You gonna get it from good ol' Bone-ly skeleton like me...
