Hi, my name is Jinjoo, that was the name given to me by Hyesung-ssi, I'm 174 years old, I live in a nice flat with him and his dog Muri. Hyesung-ssi taught me how to speak. He also takes care of me. He's rather bossy at times when his friends come over, telling me to keep quiet and wait, but I understand why. After all, I'm a half dolphin or at least that's what he thinks, I don't really know what kind of fish I am.
