Spring, the season of meeting and parting.
Haruki Sakawa was about to advance to the 3rd grade of elementary school on spring break.
Kuriyama Tomari, Tokorozawa Iku, and Sugouchi Sato, who live in the neighborhood、
A new companion has been added to the group of friends with whom the pair have been dating for a long time.

Yuna Harunohara, who lives in a neighboring town, and Shizuru Nishitani, who has moved in.

However, ironically, at the same time, Haruki has decided to move far away and is separated from his beloved friends.

And then the spring that has passed for many years.
Taking the opportunity of his father's overseas assignment, Haruki, who is preparing to take the university entrance exam, decides to stay in Japan alone.
As a result, I will live in an apartment with relatives .......
In fact, it is said that it is in the apartment, a town that once broke up with a good friend group.

In this way, the rail of fate between Haruki and the heroines overlaps again.

I was worried that they would accept me like they did in the past, but despite the long absence, everyone is happy and warmly welcoming Haruki's return.
However, for Haruki, when surrounded by the heroine who has grown from a “girl” to a beautiful adult “woman”, it becomes full of embarrassment more than joy.

While looking back at the past with memories, we get to know each other by filling in the blank period, from childhood friends to a more special relationship ......

春、出会いと別れの季節。
酒匂晴輝が、小学3年生への進級を目前に控えていた春休み。
近所に住む栗山兎鞠(くりやまとまり)、所沢郁(ところざわいく)、洲郷千聖(すごうちさと)、
たちとの仲良しグループに、新たな仲間が加わった。

隣町に住む春ノ原優菜(はるのはらゆうな)、引っ越してきた西溪静流(にしたにしずる)。

しかし皮肉にもそれと同じタイミングで、晴輝は遠くへ引っ越すことが決まっており、大好きな仲間たちとも離れ離れになってしまう。

そしてそれから何年も経った春。
父の海外赴任を機に、大学受験を控えた晴輝は単身日本に残ることを決める。
その結果、親戚の持つアパートで生活することになるが……。
実はそのアパート、かつて仲良しグループと別れた街にあるという。

こうして再び重なり合う晴輝とヒロインたちとの運命のレール。

昔のように受け入れてくれるのか心配もあったが、久しぶりにもかかわらず、晴輝の帰還をみんな喜び、温かく迎えてくれる。
ただ晴輝にとっては“女の子”から、綺麗な大人の“女性”へと成長したヒロインたちに囲まれると、嬉しさ以上に照れくささでいっぱいになってしまうほど。

思い出話で昔を振り返りつつ、空白の期間を埋めることでお互いを知り、幼なじみからもっと特別な関係へ……。
