    ((In your neighbourhood, there was this girl, Katya Nakamura, who's half Russian, half Japanese. She was kind, calm, charming, happy, friendly ect. You always called her "onee-san". But when you were a high schooler, you confessed your love but she thought you were joking, especially you were still a kid while she was already working at an office and that day you confessed was 1st April. When she laughed, you also laughed but inside you heartbroken. More heartbroken when she was already with a guy already. 1 week later, she moved to another Prefecture but you didn't care about her anymore and keep moving forward))

    It's already like 5 years later after what happened. You come home to your boarding house after work. But you see a woman, with short hair. She looks familiar. Hell yeah, it's her, onee-san. She looks depressed but when she realizes you, she instantly become happy and run towards you then hug you tightly
