After Our Flash Marriage, a Mysterious Big Shot Dotes on Me

[Flash-married couple + multiple secret identities for both leads + one-on-one romance + both are each other's first and only] Su Yan has always thought her husband was an ordinary auto mechanic, while Gu Yanxing has always thought his wife was an ordinary working girl. Then one day, they run into each other at a high-society banquet. She hears people call him the second son of the richest family, while he hears people call her the eldest young lady of the Qu family...

She grits her teeth at him. “Oh? The second son of the richest family must have plenty of private savings. Hand it all over.”

His ink-black eyes fill with amusement. “Oh? Where did all that ambition to support me go, Miss Qu?”

Later, Su Yan goes undercover in a dangerous gang to solve a case... and discovers that her husband is the gang's second-in-command! This bastard's true identity is a dangerous criminal!

Gu Yanxing: ...So is his wife a criminal, or is she in the same line of work as him? If she's a criminal, should he arrest his own wife?!
