After Being Forced into a Marriage, I Fell in Love with My Mortal Enemy

[The blurb has been screenshotted and saved]

Zhong Liu is a notorious playboy in the capital. He'll do anything but something respectable, and he especially loves picking fights with Qi Yu, the marquis's legitimate son.

If Qi Yu spots an antique zither he likes at the Eastern Market, it'll be in the Zhong residence the next day. If Qi Yu casually writes a poem that earns praise throughout the capital, Zhong Liu immediately writes a hundred poems and spreads them through every street and alley. Then one day, the Qi family and the marquis's household arrange a marriage, betrothing Zhong Liu's elder sister to become the marquis's wife. On the day he sends his sister off to be married, Zhong Liu looks thoroughly put out.

But he never imagined that Qi Yu, who seemed so delicate and frail, would plot a rebellion, massacre the capital, and leave the entire Qi residence awash in blood. His married sister dies with her neck broken, her eyes still open.

That day, under rolling black clouds, Qi Yu approaches him in a black robe edged in metallic gold, stepping through the blood. He lifts Zhong Liu's chin and sneers, "...Do you know why I chose the Zhong household as my first target?"

"Because the person I hate most in this life is here."

Reborn before his sister's wedding, Zhong Liu jolts awake from a nightmare. Determined to prevent the events of his dream, he decides to move the whole family away, but fails. Then he decides to warn the Crown Prince early so he can prepare, but that fails too. In the end, Zhong Liu tries every means he can think of to stop the marriage, and, predictably, fails yet again.

On his sister's wedding day, Zhong Liu grits his teeth, knocks her unconscious, and takes her place in the bridal sedan. Qi Yu hates him to death, doesn't he? Then he'll go right up to the menace himself and kill his enemy first!

The wedding candles burn, and the bridal chamber is silent. The man in wedding robes, his expression cool, lifts Zhong Liu's veil, takes out the little dagger he had prepared for the assassination, and raises an eyebrow.

Zhong Liu, whose mission has ended before it even began: …

The pretty young man, radiant as a flower, immediately changes his expression, looking shy and bashful. "I've admired Young Master Qi for a long time. This is something I prepared myself... for our private entertainment."

Qi Yu replies impassively, "Is that so?"

Everyone knows that Qi Yu, the marquis's legitimate son, is ruthlessly ambitious and has endured for more than a decade to achieve his grand plan. When his rebellion succeeds, no one dares defy him; all bow and submit.

Who could have guessed that enemy soldiers would launch a night raid, seize a hostage, and tie Zhong Liu up in front of their troops as a living target, demanding that Qi Yu come out and die?

Zhong Liu: ...Bro, you've got the wrong guy!!

In the next instant, the man who kept saying he hated him appears like a god from the heavens, shoots the enemy commander dead with an arrow, then rushes over and embraces Zhong Liu, his arms trembling.

Zhong Liu's eyes widen. "Y-you don't hate me?"

Killing intent roils in Qi Yu's eyes. "I hate you..."

He hates the countless days and nights of loving him alone, with only the moon hanging high to keep him company, while the person he longs for has never once looked his way.
