Cover and New-Series Announcement

The Cover Immediately Introduces Three Romantic Directions
Fantasia Bunko is presenting the title as a new romantic-comedy series, using the cover reveal as one of its first major promotional beats before publication.
The artwork prominently places the three heroines at the center, matching KADOKAWA's key hook: within a single day, the protagonist's romantic life suddenly branches in three directions at once.
The title itself summarizes those events—the student council president's confession, a reunion with a childhood friend, and an arranged meeting with a Nordic girl—so the basic setup is presented openly rather than held back as a twist.
The Student Council President Has Loved Him Since Middle School
The first heroine introduced in the official synopsis is 椎葉詩緒, the student council president admired across the school.
On the day that launches the story, she reveals that her feelings for the protagonist actually date back to middle school. Her confession becomes the first romantic development to arrive that day.
The initial material does not yet explain how their earlier relationship developed or why she waited until now to confess, leaving that history for the novel itself.
His Childhood Friend Returns and Confesses Too
The second route comes through 五ヶ瀬来夏, an upbeat gyaru who has just transferred in and quickly becomes the center of attention in her new class.
For the protagonist, however, she is not a stranger. 来夏 is his childhood friend, making the same day a reunion after time apart.
The reunion does not stop at nostalgia. KADOKAWA's synopsis makes clear that 来夏 also confesses her feelings that day, immediately complicating a situation that had already changed with the student council president's confession.
The Arranged Meeting Turns Into a Proposal
The third heroine is 撫子エルヴシッド, a company president's daughter described as a Nordic beauty.
She meets the protagonist for the first time through an arranged marriage meeting initiated by her father. What begins as a formal introduction, however, accelerates much faster than expected.
撫子 explains that even if her father created the opportunity, she has come to value the protagonist's heart. Their very first meeting ends with her proposing marriage.
One Day Starts Three Romantic Comedies at Once
KADOKAWA explicitly describes the setup as three simultaneous romantic comedies. The appeal is therefore not a slow process of discovering possible love interests, but watching the protagonist manage three relationships that all become active immediately.
Each heroine also enters from a different foundation. 詩緒 brings feelings carried since middle school, 来夏 brings a childhood bond that has suddenly been restored, while 撫子 represents an entirely new relationship beginning through an arranged meeting.
That distinction gives all three a different reason for entering the protagonist's life instead of building the entire romantic conflict from one shared situation.
Launching September 18 Under Fantasia Bunko
KADOKAWA has scheduled the light novel for release in Japan on September 18, 2026 under the Fantasia Bunko imprint.
The physical bunko edition contains 312 pages and costs ¥902 including tax. Its ISBN is 9784040765976, while Amazon Japan uses 4040765974 as both its ASIN and ISBN-10.
Preorders are already available through Japanese retailers. As of the initial announcement, no anime adaptation, manga adaptation, cast or dedicated promotional video has been announced.
Why This Matters
1) The premise activates three romance routes immediately
The story does not spend multiple arcs introducing possible love interests one at a time; all three heroines enter the protagonist's romantic life on the same day.
2) Each heroine represents a different relationship
The setup combines long-held feelings from a student council president, a childhood-friend reunion and an arranged meeting that unexpectedly becomes a proposal.
3) The romantic conflict already exists at the opening
These are not merely future possibilities—each heroine takes a concrete romantic step from the beginning of the story.
4) This is a completely new Fantasia Bunko series
The September release begins the series from Volume 1, leaving the balance among its three heroines and the protagonist entirely open.
