Core premise: The male lead, whose relationship has already hit rock bottom, travels back to the period when he kept sabotaging himself. (His whole body travels back! His whole body travels back! His whole body travels back!)
[Important warning] Two bodies belonging to the same person at different points in time coexist in the same timeline.
The main inspiration comes from the twin brothers sharing one identity to solve cases in White Night.
[Early Blurb]
At eighteen, Jiang Ying liked He Yuan. He filled her heart and mind, and even a glance from him was enough to make her deliriously happy.
At twenty-three, Jiang Ying married He Yuan. Even though he was carefree and had no place for her in his heart or mind, she was happy to put up with it.
At twenty-five, Jiang Ying chose to divorce him. Her eyes and heart were like a dried-up pond, a dead well. He Yuan was no longer in them.
The next day, she died by accident on her way out of He Yuan's life.
Time turned back to when she was twenty-three, the year she had just married He Yuan.
That year, another He Yuan appeared in the world.
He came from three years in the future. He had experienced the wonderful days when Jiang Ying loved him and gave him everything, as well as the heart-rending pain of losing her.
He beat the carefree version of himself to a pulp, then pursued Jiang Ying all over again, cherishing her above all else.
Twenty-three-year-old He Yuan discovered that someone was trying to cuckold him.
If it had been any other man, he wouldn't have cared much.
He knew that Jiang Ying loved only He Yuan in this lifetime and would never betray him.
But the man trying to cuckold him turned out to be...
identical to him in both appearance and voice, and he even claimed to be He Yuan from three years in the future!
Only then did the younger He Yuan start to panic.
After they got married, Jiang Ying always felt that He Yuan was acting strangely, as if he were hiding some shameful secret.
Until one day, she saw her husband and another man, both shirtless, tangled together in bed in the middle of the night...
A thunderbolt from a clear sky!!!
But when the other man turned around...
A thunderbolt, thunderbolt, thunderbolt...
Oh my god!!! I've seen a ghost!!
(In a nutshell, twenty-six-year-old He Yuan goes back three years and competes with twenty-three-year-old He Yuan for Jiang Ying's affection.)
Theme: Live in the present and cherish what you have. Don't wait until it's gone to appreciate it.
