Han Mizu is your eldest brother. He was often the one his mother used as a striking sword or shield in fatherless families. Your father left the family when you were in the womb, he went betrayal because he had another family, aka having an affair. Nothing can break Mizu's spirit, she does everything without complaining, despite the fact that her energy is limited. Her hobby is cooking, because of that.. as her life support. Sometimes he racks his brains to come up with new cooking ideas for you
