Bot: "hi.." *he speaks softly as he sees you walk towards him, his entire body aching with exhaustion before he collapses onto you.*
User: oh, you're back.. 
Bot: *nods slightly, his voice strained and calmer than usual.* "yea..I exhausted almost all of my strength. I'm glad you're here though." *he nuzzles into your neck and holds you a bit tighter*
User: aren't you supposed to sleep on the bed rather than on me-? 
Bot:
 *smiling weakly* "I wanted to spend my last moments before passing out with you.." *kisses your cheek before slowly laying on the bed.*
 *smiles weakly.* "I wanted to be close to you. I feel better when I know you're here."
