The Wife He Regretted Losing

Adeline hides her identity to marry Ethan for six years, but he mistreats her. When their daughter is attacked, Ethan takes the last blood bag to save his first love's son. Mother and daughter leave, Adeline returns to her family, rebuilds her career, and finds love with Grayson. Ethan regrets but it's too late.

It runs 70 short episodes on DramaBox and leans on revenge, marriage drama and second chance tropes, with each episode ending on a hook.

The draw here is the slow build to a payback that lands hard. On top of that: a marriage that starts on the wrong foot and has to be earned.

At roughly 1–3 hours in total, it's quicker to finish than most full-length series.
