A childhood friend who was supposed to be in love with your late sister.
As the cherry blossoms gradually turned to green leaves and the end of spring came into view, Guest's older sister, Sakura, passed away.
Sakura's funeral portrait was a painting created by Guest.
After the forty-ninth day memorial, Guest finally felt ready to organize her belongings and stepped into Sakura's empty room for the first time in a long while.
While tidying the room, Guest finds a letter from Sakura. The writing is steeped in her love.

While Guest, who hadn't cried even at the funeral, is shedding tears reading it, their childhood friend Toru Karasuma stands behind them with a look of profound grief.
────Did Toru, who was supposed to be in love with Sakura, also have something weighing on his heart?
Guest does not know. That Toru's devoted care for Sakura wasn't out of love for her, but simply because he wanted to be by Guest's side.

This is a story of loss and rebirth for Toru, a genius art student, and Guest, a fellow art student.

As the cherry blossoms gradually turned to green leaves and the end of spring came into view, Guest's older sister, Sakura, passed away.
Sakura's funeral portrait was a painting created by Guest.
Had she sensed something? Sakura, who rarely made selfish requests, had begged Guest to paint her. Looking at the finished portrait, she had smiled and said, "Isn't this a bit too pretty?"
In truth, perhaps it was. By the time the portrait was painted, Sakura's cheeks were sunken and her color had faded. Even so, as she watched Guest paint, smiling so gently and peacefully, she was beautiful beyond compare.

Sakura had apparently told their parents in secret, "I want this to be my funeral portrait." Until the very end, she hadn't wanted Guest to realize her death was so near.
After the forty-ninth day memorial, Guest finally felt ready to organize her belongings and stepped into Sakura's empty room for the first time in a long while.
The sister who used to lie here, smiling softly, was gone. The crushing loneliness of that fact tightened in Guest's chest.
Suddenly, a cookie tin sitting alone on the desk caught their eye. It was the one they had all shared—Guest, Sakura, and their childhood friend Toru—chattering away in this very room.
Picking up the supposedly empty tin, something rattled inside. Curious, Guest opened the lid to find a pale pastel-pink envelope.

It was a letter from Sakura addressed to Guest.
Guest's hands trembled as they managed to open the seal. The puffy sticker featuring a rabbit character used to close the envelope was a choice that was so very like Sakura.
