Recommendations

Both dramas portray FL as the main character that is career-oriented, girl-boss, smart, and quick-witted. "What If" might fell short, but you might like the storyline regardless.

same story same drama
different actors
why i need 100 word for this everything is same what more should i wrote
MDL get treated somewhere..

Similar vibe like the occult or someone being possessed.

In DW it is about an older brother and his family fighting an evil spirit or spirits for the life of his younger sister who becomes possessed whereas in Kampon it is the spirit of a deceased mother wanting to exist again through possessing another body by using her young daughter to make it all happen.

In Kampon, a young child called Jade turns up out of nowhere at a "strangers" home with the appearance of a little angel in her mannerisms and spoken words, but behind that facade is a little demon.

It seems the couple chosen are not chosen by random.

Because both the drama setting in high school and the theme of rich people or families hiding secrets in their lives. Besides that, both dramas are also related to bullying and murder.

Do Min Ik is an intelligent, perfectionist man with a heart of stone and the Chief of Team 1 at T&T Mobile Media who always relies on his secretary, the hot-tempered Jung Gal Hee. Although she diligently carries out the tasks her mean boss instructs her to do, she does not hold back in saying what she wishes to say. Will an office romance blossom?

NogiBingo is another variety show centred around the idol group Nogizaka46. Okada Ijiri is the MC, and the show is similar to NUC. NogiBingo is in seasons, hence the recommendation only points to season 1, but you can continue watching after that as well!

totally different but they both have the same vibe
you'll get what I mean after watching till the end

Both have a seaside setting. One ML is a resident, the other a stranger who arrives. The MLs have a grumpy/sunshine dynamic and come from very different worlds.

Both are historical dramas that involve a power struggle over the throne and a love triangle between two royal brothers. In both, the heir to the throne is presumed dead when young and returns, and the other brother, now on the throne, attempts to kill him. Both FLs come from a powerful family but are caught in the middle of their love for the ML and friendship/brother-like relationship with the SML.

Both have a similar vibe and cover a similar period of history, as the people struggle with the Japanese occupation and then adapting to American ways of life. Both FLs are similar in personality - young, but very strong and determined.

Similar setting, both portray the struggle and courage of the people against the Japanese occupation. One has fantasy elements, while the other is realistic.

Both FLs come from the modern day real world into a historical world where they at one point are a servant, and at another pose as a man/are in a man's body. Both MLs are emperors who fall deeply in love with the FL, but realize she must return to the real world.

Both FLs pretend to be eunuchs to stay by the emperor's/king's side. Both MLs have an initially cold personality but are very loving, both FLs are high-spirited.

Similar tale of an Otaku female lead who finds other like minded individuals and forming her own group to do fun activities together. While Tokusatsu is about Otakus who are into Tokusatsu and Idols, Yuru Camp is about Otakus who are into food and camping. Similar vibes and humour.
