Both are mystery-thriller dramas and they both have an 'investigation' to find the 'culprit' behind the act. 'Rumor' is somewhat darker than 'Find me if you can' (which has lighter moments). Both dramas are based on real-life topics: 'Find me if you can' is based on stalking and also showcases bullying. kidnapping, manipulation. While, 'Rumors' is based on rumors (obv) and their effect on people, being a victim of workplace bullying and judgement.

Unproblematic and mature love story

Follow the lead through years
Incredible chemistry between the leads
The give the same "good/romantic" vibes

Both are contemporary hero shows, that aired around the same time, focusing on a pair of characters - the Minato brothers in R/B and the "best match" guys in Build.
There are also fourth wall breaking "previously on" segments for both shows.

The biggest difference, at least in my opinion, is that Ultraman R/B has multiple, actually well-written female characters. (And it also does not have a 29-year-old man/19-year-old woman relationship.)

both dramas are supernatural fantasy that deal with curses! mirror deals with a girl whose cursed by love. anyone she loves or who falls in love with her, dies!

both are supernatural fantasy that deal with curses with strong female protonagists whereas mystic deals with a 2000 year old curse, deals with a 5000 year old curse of a goblin whose curse can only be broken by his bride who will also cause his death!

both dramas are supernatural fantasy that deals with curses!
both have strong female protagonists that are cursed! mystics cursed owner lady has been cursed.over 2000 years and has to perform or rather help like 1000 souls in order to break the curse. In mirror the girl has to light like a 1000 candles to break her curse but the evil shaman that created the curse tries to blow out the last like 20 candles using dark magic!

both fantasy dramas deal with supernatural curses that with strong
single female characters whose both cursed! hotel del luna owner, whose been cursed.for over 1000 years that can only be broken if she finds true love but first she has to let go of her 1000 year old resentment of the betrayal from her first love! whereas mirror of the witch aka secret healer has been cursed over 5 years and anyone who falls in love with her or that she falls in love with , will be cursed !

The main similarity is there's someone/ something killing the students at school.
In The great shaman Ga Doo Shim, the principal has the evil spirit target the lowest ranking student, while in nightmare teacher its the teacher who makes the student disappear

Both are thrillers with supernatural/fantasy elements with some touching and sometimes sad stories.

This is also a kind of dark love story, nothing sugar coated, with mature beautiful lovescenes. If y like this movie y sure like the cornered mouse too.

- Focuses on a man and a woman's journey through a zombie outbreak
- Zombies rampant
- Locked in an apartment block
- Friendships and betrayals along the way

I feel some kind of similarities in the atmosphere...

The relationship in One Ordinary Day between the ML and the king of the prison made me think about The merciless (but we'll have to see how the drama evolves haha)

Both miniseries involve a small establishment with thoughtful, down-to-earth employees. Many customers seem to be struggling with personal problems that the employees empathise with and aim to resolve or make better with a relaxing drink and a heartwarming chat.

1) In the both drama's the male leads know each other from childhood.
2) In both drama's the female lead's kind of bullied the male lead.
3) Both female leads work as assistant for the sport's team.
4) Both fall in love later on

Both Japanese dramas revolve around food and everyday life. Wakako Zake is about a woman who enjoys drinking and eating different dishes based on how her day went.
