That year, he was nine years old and she was six years old, when they first met
In the same year, they made a promise from the bottom of their hearts
In the same year, they experienced a moment of life and death together
In the same year, he forgot about her and she was forced to leave him
This year, he is nineteen and she is sixteen. She found him, but unfortunately she still has to leave.
In the future, do they have each other in their future?
