Why did Zhang Wansen jump off a building?

The reason why Zhang Wansen jumped off the building was also for Lin Beixing, because her brother owed a usurer to run away and the debtor wanted to arrest his sister Lin Beixing. In order to protect him, Zhang Wansen led the debtor to the lighthouse. Finally, he was pushed off the lighthouse and died.

"Twinkle, twinkle, twinkle, bright star" tells the story that Lin Beixing accidentally deleted the old mobile phone text messages and went back to high school to get to know Zhang Wansen again, and the two of them helped each other grow up.

Ending:

Those' I like you' that can't be said in parallel time and space have always been in the eyes of Zhang Wansen and Lin Beixing. In the end, many people said that Zhang Wansen was not the one who gave her an umbrella, but careful netizens saw the song in the last episode.

I am glad that the figure is Zhang Wansen, and all the regrets can finally be completed at that moment. Zhang Wansen is no longer the shadow knight who will only silently guard her and can be guarded by her.
