Both are about cheating and affairs. Both "mistresses" are villains tho R&D yoo hee is more a Rael than Eve's Rael. She has no attachments and she twists everything to her advantage
The wives are opposites, with Sora being a psychopath, and hyesung has more opportunities to have revenge

Both have two "worlds" and 2 characters that travel through them. One needs shock and the other needs death.

Makjangs are a hit or miss. They can be unbelievable crazy or elegant crazy. And these two are the later
They're dramatic and extreme but it's no penthouse and it's not boring
There are characters to root for, mainly fl and her sweet sls vibed partner in crime.

Both have jingoo and both have a bit of connection with memory and feelings sharing. Circle was scifi but link is maybe a magic?

If the love alarm app was a human it'd be Eun Gye Hoon xD there's a bit of "connection" and empathy but in a magical way

Both are focused on food and both have a murder mystery thrown in the romcom vibe
Might also share the style of friendship and slice of lifeness

When BYH 1st goes to the voice phishing office and got his red numbered jacket it felt like a scene from Squid Game
The basic idea was the same, guy goes undercover in a place that lied to people and used their weaknesses for money and entertainment

Both are makjang and deal with crazy moms and their crazy expectations for their kids.. and they both have traumatized kids that need heavy therapy

Both are aired at the same time and both are comedic crime mysteries with a side quirk
Tho one is about ghosts but both are about non cops investigating and the fls are cops

I always thought Jin Ki Joo was a total Kyoko. Her cute slightly clueless behavior mixed with her talking back and not taking people's bs
Opening scene in p3 of FNOS was really like a scene in SB where kyoko is just oblivious while "helping"

Both have that "nosy" normal citizen that loves to snoop around too much
And both also have cops that end up helping the normal citizen

A "supernatural" ML with the cute overzealous FL mix up
Tho Lee Dam was a total gen Z, I don't think seul hae is a gen Z but she's being cute millennial
