The Scumbag's Three-Step Plan: Redeem Himself, Have a Child, and Find a Boyfriend

Synopsis:

Jin Changshen is taken back twenty years by accident by the Scumbag's Redemption System.

He suddenly discovers that, aside from this life, he has been a bad person in every life he has ever lived.

The useless System malfunctions after installing a pregnancy module. It tells Jin Changshen that he must either start completing missions in this life or be trapped here for all eternity, until his soul is ultimately obliterated.

Jin Changshen, who has PTSD from being forced into things, gives a cold laugh: "I'd rather die than do missions and bear children for other people!"

[World One: The love interest is still a good person at this point.]

But right after being reborn, he spends a night tangled up with Su Jingtang, a stranger who died young in his previous life and somehow ended up on his household register as his former wife.

When Jin Changshen learns that Su Jingtang, who died young in his previous life, was the reason Su Jingtang's older brother targeted him during the first half of his life, he wishes he could run to the ends of the earth and never see the culprit Su Jingtang again.

But later, the two go from mutual dislike and hidden agendas to testing each other, then falling truly in love.

In the end, to keep Su Jingtang from dying young, Jin Changshen, the gong, willingly bears a child himself.

But after a few years of happy life, Su Jingtang mysteriously disappears.

To find his beloved, Jin Changshen has no choice but to begin his missions and enter the lives in which he was a bad person.

Redemption, finding a partner, having children: Jin Changshen becomes a specialist in giving birth.

[World Two: An obscure boy-band member will do anything to rise to the top, including drugging...]

Jin Changshen is an overlooked member of a boy band. Vicious and vain, he'll do anything to make it big, including drugging the gold-medal manager, the shou.

The gong escapes from the bed and falls into a lake, losing his memory by accident. The poor puppy is found in the hospital by the unsuspecting gold-medal manager, who takes pity on him and gives him a chance, promoting him as an actor...

Later, he becomes the gold-medal manager's darling.

Even after having a child, he's still the gong!
