The flower language of blue iris is "broken hope".
At the age of sixteen, Shen Huaian was the worst in everyone's eyes. Only Jiang Yuan drew an iris on his desk and said, "Sword-shaped leaves can bloom, and so can you."
She taught him gentleness, but he used this gentleness to guard the border.
He said: "Little Kite, the iris on the border is as blue as ours. It turns out that the flowers don't recognize the boundary markers."
Later, his comrade-in-arms fell into the blue, and his spirit was also shattered into the blue. Every letter he sent was painted with an iris, from straight to twisted, from blue to black.
Ten years later, Jiang Yuan became an art teacher. The boy she taught painted everything like an iris - crooked, but pointing upwards.
The boy said, "Teacher, my dad has a half-burned painting at home. He said it was the only thing he didn't want to forget in his life. When he was sick, he always called out a name, 'Iris'."
Iris.
Both the iris and the light in her eyes.
The fire burned half of the painting and her right hand, but it could not burn away the blue mountains and plains in his illusion.
On the day Jiang Yuan disappeared, she left only one sentence in the studio: "You said flowers don't know boundaries. But my boundary is you - if you cross it, there will be no spring in my world."
