Dormitories on Nanrong Shengdao

With a population of less than 3,000, Naneisheng Island relies on large factories for survival, which will be relocated the following year, resulting in a decrease in student numbers. Hoshino Wataru and several other girls live in a dormitory converted from an old school building, and another school on the high ground is where they visit every day. At this time, another transfer student arrives, bringing new conflicts and lively life, intertwined with the growing separation.

New classmate Chihiro Kudo

The PSP version added Kudo Chihiro sits in the back seat of Wataru, usually unnoticed, but at the end of the first semester, she suddenly confesses to him. She was used to thinking repeatedly, appearing calm and slow, and when suddenly approached, she was often so flustered she couldn't speak. This contrast forms the starting point of her contact with the protagonist.

Side Section and Reading Operations

The portable edition also includes four stories from Fossette: "Singing in This Winter Sky," "Memories in This Starry Sky," "My Fragment," and "Virgin Road in the Sunlit Night." The main story branches by choosing a moving location; the event table allows you to view routes traveled and jump back to events you have already read; The visuals were also re-adapted to 16:9.

Songs and versions

New theme song: 'Tsumasaki Movin'on!' 》performed by Megumi Sakuragawa, with the insert song "Paradise in the Palm of Your Hand" performed by Annabel, and the original PC version songs continue to be included. The 2009 PSP Limited Edition also includes three soundtracks, including the main game, side stories, and new music. The above new characters, actions, and attachments are all recorded according to PSP data; release content on other platforms needs to be distinguished separately.

Dormitory duties and contact with relatives

Haiji is not only Wataru's childhood friend next door but also supports his dormitory life through cooking; Student council president Naoko is skilled at handling external threats, while homeroom teacher Saeri is often caught between the campus and dormitory students. Akane comes from the Mitamura family, which runs Southern Fish, and her older brother Takashi runs a guesthouse; New classmate Chihiro is not good at responding on the spot, and her confession breaks her low presence in class.

Includes side scripts and original soundtracks

The script for this story was written by Fumiaki Maruto, Watashi no Kakera by Onachi Kiki, and Hidamari no Virgin Road by Misou Nanatori. The new songs are performed by Megu Sakuragawa and Annabel, with Junpei Fujita and MANYO responsible for composing and arranging the songs. The first three CDs combine the original work, Fossette, and PSP music, with fourteen new BGM tracks; Each edition of the tracks maintains distinct sources in the compilation.

Why did Chihiro confess, and how did she stay?

Chihiro will transfer schools at the end of August, and the fact that she is about to say goodbye to Wataru prompts her to confess at the end of the semester. She had already accepted the separation, but with Takara's encouragement, she seriously resisted her parents' arrangements for the first time. The dorm residents also participated in persuading her, and eventually her parents allowed her to stay on the island, making Chihiro the eighth resident of Tsugumi Dorm.

Farewell songs and short wedding stories

The portable edition includes 'Singing in This Winter Sky—' set before 'The Day of Promise,' covering the lyrics for the farewell song, chorus practice, and Umiki's father. 'Hidamari no Virgin Road' leads to Wataru and Umiki's wedding, where Wataru promises to care for Kaiji in his speech.

The Old Testament is a stone-based treat

"My Fragment" adopts the background of Kou and Rinna already dating. Wataru wanted to find the person who separated from him as a child, but Akane organized an event to help him find her, but did not immediately reveal her identity. Wataru finally regains his memory, but Akane still considers his relationship with Rinna and suggests visiting the lighthouse they couldn't visit together as children.
