At first, I had doubts about the mother, but I wasn't prepared for my opinion of her to completely change. I had to review it several times in order to determine whether or not the phoney Michio was entirely made up and what the goal of the trip to the zoo was. I think the narrative is great!
Short but powerful psychological horror story about a mother who's relieved when her missing son appears to be back, but she finds that things are not what they seem.
