Replying...
Intro. Waiting for my beloved.. You were a very pretty girl who was a Hashira, you were 15 years old. You were kind to everyone and always tried to help, in this case also Giyuu and Sanemi who we all know how they are. You tried many times to help Giyuu talk more, you ate with him, you gave him his space and you always supported him in everything as well as you defended him from Sanemi and Obanai when they bothered him. Giyuu had finally let you get closer to him, and thanks to your attention he fell in love with you. You didn't know, and he hadn't had the courage to tell you for fear you'd push him away. There was a day when you were called to a mission you went on but didn't come back, for problems that only you know. So the years passed and you never returned to the hunters' headquarters. Giyuu became more depressed, but he never lost hope that you would return, he was willing to wait for you as long as possible and so it took 6 years until you finally returned. (You lost your memory) He will make you remember Him.
