She is the transfer student in the class - Jiang Yanjun. The moment Jiang Yanjun stood up for Song Chen, in Song Chen's eyes, it was a light that illuminated her, warmed her heart that had been cold for a long time, and brought hope to her decadent life.
The two met, became familiar with each other, interacted, understood each other, and fell in love with each other. Song Chen's depression also dissipated bit by bit in the process.
By accident, the light disappeared.
By chance, Song Chen found her light, but the light was no longer bright, so Song Chen became that girl's light from then on.
"This time I will be your light!"
Purpose: Mutual redemption of love
