Plot High school student and aspiring artist Yuki Hase falls in love at first sight with Kaori Fujimiya after the latter narrowly manages to pass down a borrowed French dictionary Yuki left behind inside a train. To his joy, Yuki learns that he and Kaori share class for their second year. However, Kaori seems to have forgotten their meeting. When he introduces himself again, she rejects his offer of friendship. Yuki later finds out that she has similarly rejected other offers since her transfer 3 months ago and is thus regarded as a pariah within the school. Nevertheless, Yuki strives for Kaori's friendship, gaining the attention of his teacher, Mr. Inoue. Inoue tells him that due to an accident, Kaori suffers from both retrograde and anterograde amnesia; any memory other than that of her parents is suppressed after a week. Undaunted, Yuki has made up his mind to become Kaori's friend in any way. To remind her of him and other things, he gives her a shared journal, where the two can share their memories every week. By this method, the two slowly grow closer and Kaori becomes more and more open.
