Under Blossoms: The Friendship Route

Her life was gray. Shades upon shades of gray, black and white. There was no color, it did not call upon her.
His life was color. Tints and shades and brights and darks, pastels and neons. The color called upon him, it was him.
In what seems to be a random occurrence, they meet. She sees color in him. He feels strange around her.
Yet, others see his color. She feels an emptiness away from him, she needs him. But..
Seeing color for once in her life made her realise how black and white her home was.
She could not stoop to her mother's level. The color would fade from him, and she wouldn't be fulfilled.
He was to be her friend. That was how relationships started, right?

Right?
