Regret Muahahah

Hero regrets it a bit when the truth comes to light
But I wanted MORE

Regrets when their engagement gets called off, though it is mild compared to other mangas on the list hehe but Still It's one of my favourites

Satisfaction: 9/10
Ohoooo hahaha this one is worth your time I betcha
LOVE YOU KANG JUN
YOONSUEL YOU BIG IDIOT, LOVE YOU TOO

A very short span of time where the ML's words come and hite him in the arse

fl loved the Duke for 10 yrs
Managed his estate with loyalty and dedication
Duke is disrespectful and Ignores her devotion
Fl had enough and goes on to propose a contract marriage with Emperor of neighbour state.
Obviously the Duke regrets and becomes as annoying as a gum stuck under a shoe

There is minimal regret
But the revenge is SWEET
angst is high though
9/10 story

Husband cheats on her with her best friend (who obviously is a bitcch and feel she is superior to fl because she is her ONLY "friend" and is actually super jealous of fl so she steals everything from her hence the husband)
Kills her and tries to claim the insurance money
Shitty In-laws
Reincarnation
Revenge
New man (super green Ml who is RICH and LOVES fl for who she is)
New better In-laws
Regret and chasing but all in vain by the ex
Super predictable plot

runs away
ml has a redemption arc but it wasn't as satisfactory (I firmly believe he should've suffered more, Also not enough groveling)
This is dumb and dumber, do not expect more
All in all package for that SPECIFIC itch

Ex husband and best friend, rides on the Fl's tailcoats all through her life. When the water rises above the head, the fl says enough and takes everything that rightfully belonged to her, back.
