The two male protagonists#apocalypse#are different in age and body shape
Jian Ning (suffer) Omega × Shen Yu (attack) Alpha
The end comes without warning.
Jian Ning huddled in the corner of the equipment room and called Shen Yu.
Shen Yu said to him: "Don't be afraid, I will be there soon."
Later, Jian Ning discovered that Shen Yu's gun was always facing the outside.
Leave your back to him, leave your arms to him, and leave him the last small piece of clean space in the end.
"The world is collapsing, and the small piece of land in his arms is sprouting."
"Shen Yu said: Others beg for life, I beg for you."
"He protected an Omega in the apocalypse, and later that Omega gave him a spring."
The plot is okay, the writing is average
