Even if you try to alienate me, I will protect you at all costs.

Every time Lin Beixing goes back, Zhang Wansen asks if you know me, not if we know him.

Every short message that can make Lin Beixing go back to the past is a moment of regret for Zhang Wansen.

If Lin Beixing didn't go back to the past, he would never know that there is a man named Zhang Wansen who has been silently guarding him in this world.

5. The dislocation of time lies in undiminished love. The past time is scattered like a jigsaw puzzle. She only picked up the first piece to piece together the whole painting, but it was close to the end of his life.

God couldn't bear to bury love in the past, so he arranged reunion again and again to make up for one regret after another.

7. The whole world is behind you, in your past, but not in your future.
