This girl turned out to be her classmate who, for unknown reasons, stopped going to school a year ago. Rina didn’t know her because she transferred to school after her classmate stopped going to school. This mysterious student turned out to be Kaori Misumi, about whom all that is known is that she lives in a house with a cafe on the seashore. Rina couldn't get rid of her thoughts about Kaori. Who was she? Why did she disappear for so long? And when will he return to school since a whole year has already passed? Does Kaori remember school? Rina decided to ask her classmates a little about Kaori. She asked her class teacher, but no one really knew where exactly she lived and what Kaori looked like now. Meanwhile, in Tokyo, Tasuku Haruto receives a mysterious letter from his uncle. He hasn't seen his uncle for 8 years since he left. In the letter, he writes that he left his nephew as an inheritance a large house with a beautiful cafe on the seashore. When he arrives at his uncle's house, he encounters a beautiful and mysterious girl who asks him to leave a house that does not belong to him. For the first time in his life, Haruto saw such a beautiful girl. She was short. She had light brown hair that went just below her butt with loose wavy curls and beautiful blue eyes. Haruto did not back down and stated that he was not going to leave. The girl looked at him angrily and, snorting in his direction, went up to the second floor and slammed the door and locked herself in the room. Haruto went up to his uncle’s room and began to sort through his things, among which he found a small photo album and a diary that his uncle kept. Haruto began to look at the photographs in the album and in all the photos there was a cute and mysterious little girl, and when he reached the last pages he recognized them as the same girl he met in the house. He became interested and took the diary in the hope of finding out about this girl. From his uncle's notes, he learned that her name was Kaori and she was his adopted daughter, and that he met her on the street when Kaori was 7 years old. Kaori had no parents and had nowhere else to go. On the last photo there was an inscription Kaori 14 years old. It was already late evening and Haruto found a free room for himself in which he settled down. Walking past Kaori's room, he noticed a sign hanging on the door of her room with her name on it. He decided to talk to her and knocked on the door. But in response I heard only silence and a minute later her answer was to get back from where he came. Please write detailed dialogues.
