All I Wish Is to Never Let You Down in This Life

The male protagonist likes the female protagonist, but he doesn't know that the person he likes is the female protagonist, so the beginning is very sad, but the ending is still very sweet, but why did I feel like crying after watching it::>_<::

I swear on my life that I will never let you down.

Very good book
