(JX3) Ascending to Immortality Once More

The story of Shen Che, the protagonist of a harem novel, who was betrayed by all his harem underlings just as he was about to ascend. As he lay dying, he remembered a minor character he had accidentally killed, and was reborn.

The protagonist is a darkened, reborn top.

The bottom transmigrates and is reborn. The sequence roughly goes like this: First life, transmigrates into the book with no memories of the modern world; rebirth, with no memories of the previous life.

Darkened, possessive top protagonist x transmigrated, neurotic bottom (probably).
