Both are japanese dramas based on josei mangas. The female leads deal with unemployment and the male lead end up hiring them.
It is about adult life, money and relationships. The two of them are funny but also real life situations.

Both are a mix of romance and drama, the romance of this show being separated by time travel (very similar to W's two world separation).

Leads have super powers, both are based at gaming companies. Both have quirky humor. Both have OTT violence. Watch for Lee Dong Wook.

The stories arent really similar but they have the same comic feel

Kora kengo is an acotr in both films. Norwegian wood is more melodramatic than yonosuke which is more slice of life and comic. Both have the same nostalgia around youth and life

Same male lead. Same nostalgic/ aesthetic atmosphere surrounding the characters

Both are about doctors who lernt this profession when thinking of understanding a medical error of the past and who are going to certains hospital when hoping to discover information. Both have romance aspect and difficulty between differents doctors and hospital director. It's seems like there is an interesting but complex plot for surgeons but the 2 dramas looks like they are nearly about the same type of stories. Maybe less about romance for surgeons and with a different type of surgery than in doctors.

Both are about doctors, even if the stories are differents with one being more on political aspect than the others. There is a competition between doctors and hospital's director who have secrets in both, witch is really interesting I think.

Similar plot..in both series the main leads end up living together because of some circumstances ; one of them can't stand the other one; both series start with "a letter of love", both girls are naive when it comes to love, etc.

Same main actors, similar plot. If you watched one of them and you liked it, def check the other one as well.

In both movies there are tomboys (well i prefer Miller, she is too hot to handle); plot is kinda similar to each-other.

Both stories are about people who fell in love in the past and are looking back on their love.

These two are both movies and I think there a sequel. Both about romance. Thumbs up

They have the same director, thus they have both cute drawings in each episode and the same music.
The lead actress of Something About 1 Percent even appears in a cameo role in the beginning.
