Both explored married woman’s mind, and showed that no one should limit her on taking other roles other than being a wife or mother. They’ve tackled realistic problems many wives are experiencing, and both have deep subjects and dark tone. Red is focused on one story, while Saka no Tochuu no Ie has multiple characters intertwined by one story.

Both are historical dramas.
The female lead pretends to be a eunuch (disguised herself as a man).

The female leads are both the same which is Ling Mei Shi and also its similar that the female lead has a special power or some supernatural power.

Not NIS agents but they're from cyber crime unit. Together they investigate cyber crime and fight against cyber crime/hackers/corruption.

They're both love stories involving people with disabilities. They're also both moving and emotional. They're also made by directors who are very serious and artistic and take chances with their work.

They're both bittersweet love stories about a handsome young man who falls in love with a tsundere girl in a wheelchair. You may cry in both movies.

Okay first of all, this movie is not about doppelganger swap places but it's about a soul who were supposed to crossover were given a second chance in life for a month.

Fl were send back to earth and needs to adapt a new life as a housewife and mom instead of being a top prosecutor. Her soul swap places with the housewife's soul who is currently in coma.

There's alot of chaos and mess happen and it's so hilarious watching fl try to adjust her new life as a wife and mom which she never experience before.

What i like about this movie is although there's a financial restraint, some conflict between husband and wife and their teenage daughter is at the rebellious stage, she try the best as she can and her husband always has her back no matter what.

Same concept of the couple falling in love in the process for filming reality show. Both are sweet in their own way

This drama has a mature relationship, non toxic relationship, communication is the key, trust each other and never give up on each other. This drama also focus on the adults in their mid 30's.
Of course there's a up and down in their life/relationship just like any other kdrama but the different is their relationship is rock solid and instead went for a breakup just like other cliche drama, they brave the storm together and always supported each other.

Both has Allen Ren as main lead. The Destiny of White Snake also has reincarnation/another life theme and great OST.

Both drama series focused on career development of the main leads.
Both drama also shows the reality of living in the big city, temptations, life principles.

Both are Taiwan crime shows, they are intense, features a strong cast, and engaging mystery/plot. There is considerable gore in each. Also have the same director.

I find the series to be a better version than To My Star(movie). It is very believable and the acting is a lot better and makes more sense.

Give it a try :)

Both are about time travel back to the warring period of japan.
There are several more similarities but i would consider them spoilers.
