Xia Shu is used to being alone.
One goes to school, one is in a daze, and one is guarding the small shop after grandma leaves.
She thought that was the end of the day.
Until someone always quietly closed the window when she was lying on the table;
Always the first to hand over a tissue after she was teased;
He always happens to appear next to her when she thinks of her grandma.
Later she found out——
It turns out that the world will really be kind to you, but sometimes, it will send someone.
Intention: The world is full of malice, but we are still willing to repay it with courtesy.
