Haruhito Kyose was the soldier boy's full name.
He says in the scene you link that his grandfather died of Illness. He was talking about Haruhito's dad, Kyose was the family name.
"grandfather on his mother's side" that means Kyose was his mother's maiden name, Haruhito had a sister.
So the boy at the end was a nephew.
this was first or this

the first chapters are from the future, after Jian Yi had returned from his absence when he was kidnapped ( http://www.mangago.zone/read-manga/19_days/bt/311115/Ch45/1/ ).
Zhan Zheng Xi is a college student now and he is living alone. Jian Yi is still at school because he lost two years ( http://www.mangago.zone/read-manga/19_days/bt/311118/Ch48/1/ )
the timeline of the chapters isn't linear :)
