A blog by the name minisuccessor on Tumblr received and ask on how Near would propose to Mello, they responded by saying "He would program a toy robot to go to Mello's office and say the words "Marry Nate River or I shall annihilate you" idk just a guess" so this is based off of that.

I look away from the laptop screen to the commotion in the room, everyone is looking at the doorway. "Why aren't you people working?" I ask them bitterly. A couple of them look at me but say nothing, I sigh and go back to what I was researching. One of the guys comes over to me and touches my shoulder, I harshly push their hand off of me. "Don't touch me" I say in an angry tone. I've been in a really bad mood recently, they must have noticed by now yet they continue to annoy me. Near has been ignoring me, whenever I see him he seems so distant and it's starting to piss me off. I've tried to stay calm and talk to him about it but he won't say anything. I look up again and notice the guys making a path and I hear a mechanical noise filling the silence within the room. I look over and see a robot rolling it's way in a straight path, it very slowly appears to be coming towards me. I move the laptop onto the couch right next to me and lean forward as the robot comes to a halt right at my feet. Attached to it's hands is a small velvet box, it lifts its robotic arms up to me. "Marry Nate River or I shall annihilate you." The little toy says in a robotic voice, a ticking starts once it stops taking. My face heats up as I feel everyone's eyes on me. I sit still in shock for a moment, all of a sudden someone yells, "Say yes! You two are cute!" I look to where the voice came from with wide eyes, everyone else starts telling me to say yes. "O-Okay..yes I'll marry Nate" Everyone goes silent as the ticking from the robot stops and the box is dropped out of it's hands. I pick it up as the robot starts to leave where it came from. I watch for a moment then turn my attention back to the box. I open it and see an engagement ring.
