Under the old locust tree on the campus of Z Middle School, Luo Fumian's youth was filled with the figures of two teenagers - the cold basketball boy Qin Senhang, who was her heartbeat hidden behind the top student list; and the enthusiastic and ruffian Tu Zexuan, who was her most steadfast companion in her youth. A miss caused by a misunderstanding caused the three people's life trajectories to completely deviate: she went to the battlefield and recorded the suffering of the world with her camera; he traveled to a foreign country and accumulated the confidence to protect her in the ups and downs of the business world; he stayed where he was and spent half his life guarding her care.
The flames of war are ruthless, and regrets will eventually become eternal. Until we meet again in the sea of flowers on the other side, the seventeen-year-old appearance and unspoken thoughts all emerge. There are no worldly distractions, no misunderstandings and barriers, the three of them watch the aurora flowing and the streams gurgling side by side, turning the regrets and worries that span half a lifetime into eternal companionship. This is a farewell about youth, loss and reconciliation, and it is also a gentle comfort for all those who are unhappy - there are always regrets in this world, but there will always be perfection on the other side.
