Jiang Ningyi, who was favored by everyone, was once the only sun in Xu Changyi's barren life. The young man firmly believed in all the promises she made and was willing to give everything for her.
Jiang Ningyi is Xu Changyi's world.
Later, the two separated due to emotional disputes. When they came back, Jiang Ningyi remained unchanged and Xu Changyi was willing to let go of everything for her.
It's a pity that in the end, only the letter he wrote to her when he was seventeen was left.
Intention: A one-sided approach will ultimately lead to losses for both parties.
