Which Mature Manhwa Have Strong Character Development?

What happens when the tormented female lead in a novel wakes up and decides to get together with the second male lead? Coincidentally enough, I'm transmigrated into the body of this tormented female lead!

When Gwyneth opened her eyes, she found herself in a webnovel she had just binge-read, and she wasn’t just a random character—she was the villain’s mother! In the story, after the tragic death of her first husband, the original owner of her body had swiftly moved on and snagged a perfect new partner, only to heartlessly cast aside her son from the first marriage, worrying he would become a burden. Now armed with knowledge of the impending plot twists and the looming shadows of her future villain son, Gwyneth glanced at her surprisingly alive first husband and groaned. With the script she had been dealt, she'd rather face a dragon than revamp this narrative! She was determined to rewrite her destiny, but how could she escape this villainous fate?

A thirty-year-old office lady, who got into an accident and is now trapped inside a novel series she loves. She was reincarnated into one of the side character extras of the story and meets in person the tyrant magician, the playboy prince, and the clueless female lead of the story.

She has been killed six times. Always by the same hands. Always by the men fated to love her. Across six lifetimes and five shattered worlds, she dies the same death — not by strangers, not by enemies, but by the one soul the universe itself bound to hers. The Emotionless Emperor kills her on palace marble. The Strongest Under Heaven beheads her at a cliff's edge. The Star Emperor pierces her with starlight in a collapsing galaxy. The King of the Dead strangles her while weeping. The Dragon Monarch crushes her in hands that were meant to hold her. And in her sixth life, broken beyond grief, she simply stops breathing on her own. She wakes before the God of Destiny — and learns the truth that destroyed everything. The God grants her one final life. One world where all five powers exist. One chance to choose differently. She enters her seventh life with no intention of choosing anything — except survival. She is eighteen, razor-sharp, and carrying six lifetimes of grief behind serene eyes. When The Iron Sovereign, The Heavenly Saint, The Celestial Emperor, The Eclipse Pontiff, and The Crimson Dragon King all look at her across the same room for the first time, she already knows their faces from her nightmares. She doesn't run. She plans. But the universe has its own agenda. And the five men who murdered her across time are starting to remember. The question was never whether they would love her again. The question is whether love — and the people carrying it — can survive what it cost before.

My mother was the villainess of a story. When I was born, the story came to its end. In the past, she was a rich heiress who drowned herself in luxury and pleasure. At present, everyone condemned her and spat in her path. After my father, the male lead of the story, betrayed her, her family went bankrupt. She knew nothing and had no skills, but for me, she was willing to learn from scratch.

One accident led to An Xin waking up in the body of her best friend. The once domineering Miss An was now suddenly the gentle Madam Ye, but this does not mean that she is without thorns. The first thing to solve, is this cold and unapproachable husband of hers that makes her pity her best friend. At the same time, perhaps squeeze a pretty penny off some hustle, and save up so she can travel. Perhaps she will find a few hunks on the way and her newfound life would not be boring at all. But wait, why is the once unapproachable husband suddenly so clingy? Good sir, I am not your wife, and marrying me is impossible. Unless...you promise to spoil me for the rest of my life, love me like nothing else, and to and over all your wealth and influence, and to be content coming home to do the chores and cook for me everyday. Perhaps then, I would sit on the couch and cheer you on!
