Quick Transmigration: The Unhinged Big Shot Is Luring Another Sweetheart

Any High-Quality Quick Transmigration Novels?!!!

Quick Transmigration, Yandere, Subtle Romance, Unhinged Male Leads, Inner Thoughts**

I'm looking for books similar to The Teasing, Sweet Beauty Survives a Love Rivalry Showdown. The male leads get jealous and compete for the heroine. Multiple male leads are fine. They're secretly crazy and dark inside, but don't dare let her find out. They might even imprison her. I want something really satisfying to read, and I'm okay with a slow-paced plot.

Please Recommend a Quick-Transmigration Novel, Aaaaaah!

The female lead was an orphan from a young age. She was adopted and raised to be used by someone, then became a top actress with incredible acting skills. She has a special fondness for bitter chocolate because the person who adopted her gave her some on the day she was taken in. After bitterness comes sweetness. After becoming a top actress, she gets bound to a System and sent to win over a villain, who might be a man...

One, Two, Three, Four, Five

Looking for a Completely Unhinged Yandere Hero and a Heroine with a Secret Identity, but a Bad Ending

Looking for books similar to Trouble! The Little Merman Kept by Mr. Ou Ran Away While Pregnant. A happy ending is fine too.
