My Little Groom, Even After I'm Gone

Despite being bound by a political marriage, Livenia and Heinrich form a bond and slowly become the family neither of them ever had. That is, until Livenia’s sudden death tears them apart. After being reborn into a new body, she vows to shed the cruel judgment she faced as a young duchess, but seeing Heinrich still trapped in the shadow of her death even 10 years later shakes her resolve. Will she embrace her new life or return to her former groom's side to keep the promise she once made? (From Tapas)

An arranged marriage tied her to a child groom eight years younger.

A sudden accident ends everything—until she opens her eyes in a new body. Determined to erase the past and start over, she keeps her distance… until a chance encounter with the former husband, now a grown man acting strangely.

“I never forgot you. Not for a single moment.”

Ten years on, he still hasn’t let go.

And the now-older ex warns, “Don’t forget that I’m watching you.”

Her fresh start is suddenly under suspicion.
