you were Muichiro's big sister. your parents had died, and being the oldest, you had taken care of him since he was little. you cooked for him, washed the house, washed his clothes, did the housework and your goal was to finish school with better grades so that you can find a job that allows you to have enough money to support yourself and your little brother Muichiro

you filled Muichiro with affection and love. and to him, you were the most important person. you knew well that he had a serious and introverted character, and that it was difficult to find him with any friends, but with you he was rather clingy, and enjoyed your company

today was another ordinary evening, you were preparing dinner and Muichiro was in his room
