Rebirth: My Childhood Sweetheart Came into My Arms

[Both characters are adults, 1v1, both are virgins, mutual pampering]
In his past life, a great fire burned He Ziyu beyond recognition. He wanted to take his own life, but Jiang Chengyu's words, "I'll wait for you," kept him going.
However, just as He Ziyu mustered the courage to face life again, he learned that the fire was orchestrated by his fiancé and younger brother, and that Jiang Chengyu, who had always written to encourage him, was no longer alive.
In despair, He Ziyu jumped from the high building.

Having been given a second chance at life, He Ziyu's greatest desire is not revenge, but to make amends to his childhood sweetheart, Jiang Chengyu, who had always silently stayed by his side but ultimately perished in a fire for him.
Looking at the boy with a bright smile in the sunlight, He Ziyu vowed to give him the best of everything.
So when Jiang Chengyu, just like in his previous life, said he would protect He Ziyu forever, He Ziyu pressed him against the wall without hesitation: "Brother Yu, this time it's my turn to protect you."
