Yukisada Tamura has become captivated by a strange girl named Komaki Matsuzawa who says that her birthplace was on another planet and she is trying to go back. One day, Yukisada confesses his affections to Komaki, but immediately following this, Komaki's grandmother dies and she has to move away. They both manage to keep in contact for a while by writing letters, though Komaki stops writing around the time of the high school entrance exams. When Yukisada enters high school, he becomes concerned with one of his female classmates named Hiroka Sōma. In junior-high, Hiroka was constantly bullied, which would cause her to stay home, eventually causing her to become isolated and helpless. Yukisada chooses not to ignore her like most of his other classmates, and instead starts encouraging her and helps her to build her self-esteem. Before long, Hiroka falls for Yukisada, and one day confesses her love to him. During this time, Yukisada has kept in contact with Komaki and has mentioned Hiroka in his letters. Thereupon, one day after a long time, a letter arrives from Komaki to Yukisada asking who exactly is Hiroka.
This one is a very short but a very sweet series. It is a very unique love triangle story and somehow it leaves you wondering while reading it who will the main character choose at the end. Although the downside of the story is that it is quite fast paced for me. By that I mean the way the characters develop their feelings for each other is quite fast. But that doesn't make the story dull since it is not focused on that. The main focus of this is who will the character choose between the two girls arount him. One who really she loved in the past or one that always wanted to be by his side.
