Jian Ming was reborn.
He was reborn thirteen days before his death.
So he knew perfectly well that thirteen days later, the person he'd once believed was the love of his life would cheat on him. He'd catch them in the act, and then the drunken man she'd cheated with would push him off the thirty-ninth floor, smashing him into a human watermelon.
Since he now knew the basic plot, he had to plan a different way to catch them cheating.
He had to avenge his own murder, at the very least, right?
In this life, Si Ye had everything he could want.
Except for the person he held in his heart. No matter what he did, he couldn't have him.
That person loved someone else. They got married, settled down, and lived happily ever after.
Si Ye was alone, drinking himself into a stupor at a bar.
He couldn't remember what happened after that.
When he woke up sober, he had handcuffs on and was accused of murder.
And the victim...
The victim was the person he'd secretly loved for thirteen years.
Then he was reborn, too.
"I'll never be able to repay him for what I owe him in this life."
It's probably a love-hate story between "I love you, I love you so much I've gone crazy trying to make it up to you and atone" and "Aha! You crafty murderer!" Hahaha.
