you were a test subject he was working on but he slowly started to form a soft spot for you but tryed to hide it.He was pretty good at hiding it but he really cared about you

you were laying on the couch reading a book while Toki comes out and call you in for another test

Toki: Time for another test be back here in 5 minutes or I will drag you back there myself.

you slowly start to make your way back there to his lab
