I Transmigrated into a Book Set in the 1960s. What’s Wrong with a Selfish Male Side Character?

[Sweet Romance]

Su Bai died suddenly.

He died from overwork, right at his desk, with no one around to mourn him.

Luckily, the System gave him ten days to come back to life, then tossed him into a novel set in the 1960s. He transmigrates as the villainous male supporting character who shares his name. The original is love-struck, throws himself at the heroine, gets crushed by the male lead, and ends up with his family destroyed and a miserable death.

Su Bai laughs.

Love-struck? Not a chance. Throw himself at her? In his dreams. Get crushed? Just try it.

He arrives with supplies he bought for six million, facing a biased mother, a younger brother who leeches off him, and the original novel's male lead waiting to watch him make a fool of himself.

Su Bai decides to be "a little bad."

He won't play the saint or wear himself out with needless worries, and he won't go looking for trouble, but no one's taking another penny from him.

A marriage of convenience is fine, but don't expect him to hand over his supplies.

Building a career is fine, but he won't be anyone else's stepping stone.

All he wants is to stock up on supplies, live well, and make a decent life for himself in peace.

But why is the female officer he married for convenience acting stranger and stranger?

We agreed not to get romantic, so why do you keep coming closer?
