Immortal Destiny

Both are mini dramas with a similar vibe, with the FLs thought of as evil and the MLs subservient to them but powerful fighters.

In both stories, the main character's heart is mercilessly torn out in a brutal act meant to control them. Though they remain alive, they are stripped of the ability to feel or understand emotions. This sets the stage for a powerful tale of love, regret, revenge, and betrayal, where the absence of a heart drives them down a path of conflicted emotions and haunting choices, leaving them to grapple with their humanity and the consequences of a heartless existence.

- Similar FL types
- ML is FL's subordinate (bodyguard in BbS, disciple in ID)
- Fast paced romance with lots of kisses
- FL is engaged to SML who wants her to gain something from her
- Kinda toxic romance
- Angsty
- Role reversal themes (more prevalent in BbS)
- Same FL actress

Main differences are the plot. BbS is a revenge romance while ID is a xianxia romance. BbS also does a lot more role reversal while ID has some RR moments but for the most part isn't.

Oh Sung Moo, the father of cardiothoracic surgeon Oh Yeon Joo, mysteriously goes missing while writing the last chapter of his webtoon "W". Yeon Joo goes to his office looking, but a hand from his monitor suddenly pulls her in, and she finds herself on the rooftop of a building, next to a bloodied man. She manages to save the person, only to realize that he is Kang Cheol, the main character of her father's webtoon. Yeon Joo later discovers she can only enter and leave the webtoon depending on Kang Cheol's feelings.

- Two of the most toxic C-dramas out there!
- Cold, intens, possessive and controlling ML, who keeps the FL captive and is stabbed by her multiple times
- FL escapes from ML's control at some point, but ML forces her to return. In Immortal Destiny he kills a lot of innocent people. In LaBF he threatens SML's family to force FL to return
- Great chemistry between ML and FL
- Super angsty
- LaBF spends more time building the main characters relationship before we get to the kiss scenes - Immortal Destiny has more kiss scenes
- LaBF has more plot, politics and characters
- Fitting endings. LaBF has a tragic ending, Immortal Destiny has an open ending
