The rom-com tone and sci-fi elements were similar, as was the sweet romance. Both relationships seem doomed due to the differences between the male lead and female lead.

Both CEO
OFFICE ROMANCE
COLD MALE LEAD/WARM FEMALE LEAD
MODERN DAY
sorry for the full caps
Im trying to reach the word limit

Same sweet style romance without a lot of angst. Different story but similar tone. Cute and light hearted.

Both protagonist work in the entertainment industry and depicts the social commentary women have to endure in today’s society.

People discover evidence that suggests spirits may be trying to invade the human world through the Internet.

Have similar romance between a perfect boss and his secretary...the boss here too has a high iq with a little dumb girl..a fluffy drama with cringe worthy moments..

Fiery Priest is not super female centered but the female characters are definitely strong and sassy. Same kind of mystery/comedy type blend and even the music reminds me of the other.
Although, not a lot of romance in The Fiery Priest, but theres definitely a moderate amount of it in Good Casting.

Both are good watches!

The main female character in Fake Princess (FP) reminded me so much of the general's daughter in My Bratty Princess (MBP).
In MBP, the female lead was a feisty lifely young woman who loved to go around in male disguise and making friends with unsavory characters to rob the rich, but in her case, it was to give to the poor.
In FP, the female lead was also as feisty and lively though her motives were more selfish in nature but she also cared for those who were part of her 'family'.
Both series involved a series of incidents which required both leads to face. Though my fave would still be Alex Su!

An investor planning on developing a tourist resort begins an investigation into the legends of the mysterious Io Island in the hope of exploiting its unspoiled beauty.

Incest relationship between a Mother and a Son as revenge.

Moebius: A housewife becomes enraged with jealousy over her husband's affair. Meanwhile, their son sits in the periphery, observing their violent confrontations. One evening, the housewife takes a kitchen knife into their bedroom to exact revenge on the father. The father though is able to repel her attack and throws her out of the bedroom. The mother then goes into the son's room and from there it hovers the family into tragedy.

Both are about delusional Patriarchs and Sect Leaders with out dated/ distorsioned and old ideas.

Mandara: Two student couples stumble upon a cult dedicated to promoting the primordial human state through rape and agriculture.

In both, ex boyfriend returns in FL's life when she's in a relationship and they kind of end up cheating.

In both, ex returns and start their relationship over again and FL gets involved with someone else but ML wins her over.
