Didn't Love You Enough

This is the story about the rebirth of a little gong with a sweet steamed bun-like little shou.
In the past life, little shou, in order to help little gong block a poisonous blade, ended up dying due to blood loss.
After the little gong is reborn he proceeds to dote on the little shou endlessly.
This is a cliche story where the second life is warm,sweet,no abuse.
