Why Did I Marry You Again? (Reborn)

My first long novel. The writing and logic aren't great, but I'm trying hard to improve! Blurb:

[Female Lead's Perspective] In her previous life, Chen Qingnian refused to marry anyone but Wen Xichen, and followed him all the way to the northwest.

But after she arrived there, her older sister died far from home, her father's business had no one to take over, her mother died of grief, and she herself met her end in a fall from a horse.

Reborn, she swore to protect her sister and mother.

As for Wen Xichen, let him go with the end of her previous life.…

[Male Lead's Perspective] In his previous life, Wen Xichen believed that once he had earned military honors and been made a marquis, he could give Chen Qingnian a grand wedding.

But he never expected Chen Qingnian to let go of his hand first. Even as she died, she never knew how much he loved her.

Reborn, Wen Xichen swore he would hold tightly to Chen Qingnian's hand and never give her the chance to let go. Nothing matters more than Niannian.

“Niannian, Niannian, Niannian!”

“I won't listen, I won't listen, I won't listen!”

One-on-one romance, both leads are virgins, the male lead has to win back his wife, both are reborn, happy ending.

p.s. This story contains lots of flashbacks to drive the plot forward.

Theme: May you be safe and well, year after year
