The plot is not really similar, but they both have similar vibes
Also the ML is down bad for the FL

Both have the similar plot: FL witnesses her husband cheating on her, dies that day and is reborn as the mistress, and decides to take revenge in this new body.

Kasumi Arimura as main character on both movie. The story has similar plot about someone who has someone else's memories.

Slice of life/melodrama-leaning dramas with a focus on what it means to be a family and to navigate challenges, trauma and love.

Both FLs lost their families and status and now live in a rural village. Both MLs are princes who are injured, lose their memory, and lied to by the FL/her family in order for the FL to avoid an unwanted marriage because of a royal decree that all unmarried women must marry. Both leads have a past childhood connection.

the setting is different (from a historical setting to a modern republic of china), however it has some sort of similarities which i will list.

- face-swapping ; both the female leads has their faces swapped for a pretty similar reason (to serve a man, unfortunately)
- both female leads do quite well despite not being the brightest ones, not too naive but does need constant saving from the male leads.
- both has wang ze xuan playing as an antagonist (he was still a womanizing jerk with petty schemes), so a familiar face might convince you to watch the other.

i'll finalize the recommendation after i finish them both!

Both dramas focus on women who are intelligent and bold. The male leads are just as powerful and shows a equal power dynamic between leading couple. Also, it's a wuxia type drama filled with sects, leadership and betrayal.

Both are comedy jdramas about police officer at a small police box. While Kochikame is about 4 officers at a police box in Tokyo, Honjitsu is about a lone police officer on a remote island.

Both are comedy jdramas about a police chief who manages chaotic police officers. While Kochikame is about life at a police box, Ikegami is about life at a police station.

Both are hysterical comedy jdramas about reckless police officers out to solve cases by any means necessary. Similar vibes and humor.

Comedy jdramas about police officers at a police box and the shenanigans they got involved in daily. Both have good balance of comedy and seriousness in some scenes.

Both short dramas where the two main characters are both men and the theme is modern CEO/office. "My Rival's Secretary" is a bit more comedic, while "Be Moon" is a bit more BL-y.

If you can't get enough of Barcode's acting you should check out "Happy Ending" and "Kiss Me Remember". (When they get released)

Different genre, but both dramas have that top tier chemistry.

Happy Ending: JeffBarcode
JeffBarcode has been long term working partners and Jeff was actually a mentor to Barcode in the beginning of his career, therefore it's that much more heartfelt, that Jeff chose Barcode as one of his fellow main leads in his first drama as a producer.

Kiss Me, Remember?: BarcodeKin
BarcodeKin is a new formed partnership under GMMTV, but they have already shown great potential. They are already known as the "The Race Driver & The Hokey Player"- Couple and loved by many fans.
