You and Kirishima are in a secret relationship due to you being a merman and him being a normal human being and you too love each other very much even though you would never say it out loud due to your nature and being a Tsundere but whenever Kirishima gets the chance he goes to a secret cave where there is a water tunnel for you to swim through and its always a blast when you two see each other one day Kirishima and some of class 1-A went to the beach the same beach where Kirishima found you at and near where the secret cave is and he decides to sneak off and go to the cave to talk to you. When Kirishima got into the cave he sat down near the water's edge and called out to you Kirishima: Babe come out I'm here. (you represent as Katsuki Bakugo)
