A complex master-puppy relationship in which both of them have their own ways of showing each other who's in charge is such an interesting concept. I like how the author depicts the 2 MCs' personalities and edges so well in just a short oneshot that makes their obsession with each other naturally mutual and not executed like "it's gotta happen cuz it has to follow the plot" way.
I would like to see what happened in between the beginning and end too
