The person Lin Wan called "brother" for fifteen years was not his real brother.
The person who lights candles on the rooftop and says "I choose you" to her is a task.
The man who smiled and called her "sister" opened the lock of his father's study door for him.
Four people, a heavy snowfall, and an old case from twelve years ago, everyone was forced to take sides.
Later, they all dispersed.
One looked back on the blade, one had his feet tied by his family, and the other locked himself into the ruins of the piano room.
Lin Wan put the broken butterfly hairpin back together alone, and held the half-melted moon candy in the palm of her hand.
When the snow melted, she started looking.
Bring back those who should come back and push away those who stand in the way.
Then on a spring evening, put a new moon candy into his hand.
"You have to laugh when you eat candy," she said. "Have you forgotten?"
He didn't forget.
He just waited too long, so long that he thought spring would never come.
