At the age of 16, the star kid Cheng Jin completely became an orphan.
Teacher Lin Qing, who grew up carefree under the care of a gentle family, saw the dangers of the world at the age of 23, and the storm that her family could not withstand was raging on her.
This year she is Cheng Jin who has nothing, and she is also Lin Qing's last sun in the abyss.
This year she is the hopeless and helpless Lin Qing, and she is also the last moment of Cheng Jin's life.
They couldn't live steadily toward the sun, so they became each other's sun.
Teachers and students, under the age of 19, save each other.
Motto: There is always hope in life
