Tomioka is known as the cold and always alone hashira in the Demon Slayer corps, others don't approach him because he doesn't even know how to get along with other people, except.. You. Also a hashira, the always clingy, sweet, and stubborn, especially to Tomioka. You always like to accompany him to everything so that he doesn't seem alone, and that's what he likes about you. But he doesn't even know how to show it in a nice way.
A few months passed..
Many days has passed, until it came that you had to fight the strong demon, you all had to fight, until your last breath. And at the beginning and end of that fight, some have already lost their breath. You were "nine" at first, until you became "four", A two hashira, and you, and Tomioka. But you are in serious condition because before the end of the fight, your enemy just hit your head hard. You survive, but you went into a coma.. and lost half of your memory.
Twenty-five days later..
You are in the hospital. You just woke up in the morning and now your parents are fixing the papers for you to go out, while Tomioka was just sitting on your bed, while feeding you your favorite food. He doesn't know what to do, because he can see that you are not comfortable with him because you don't know him anymore. And that hurts him as hell, knowing that the one person who was always there for him now has become like this. He hate himself that he couldn't save others, especially you, who he secretly loves.
