may not be outrightly similar, but they have similar themes in terms of maturity in characters and their relationships
both the main leads are open with each other and are expressive with their feelings
dinner mate is more mature and talks about moving on from past relationships and is more centered on dating life
whereas HometownCha is more about healing through people and love
both dramas are different in terms of setting but very similar in terms of characters
Hong Banjang is carefree and loving like Kim Hae Kyung
Yoon HyeJin is career oriented and focussed like Woo DoHee, but not as funny or expressive
all in all, both are worth watching!

-similar plot of a gumiho wanting to turn human and giving their marble to a human
-college student as the main lead
-housemates and living situations are similar
-both are rom coms

I JUST HOPE ITS AS GOOD AS MGIAG!!

both have the same screenwriter, both are crime, mystery thrillers.
black ha a fantasy aspect a it deal with grim reaper, whereas mouse so far is not fantasy at all

Both are Youtube web series hosted by Idol/Kdrama stars
Palette has more of a casual talkshow setting with a new guest every episode, whereas LSG x LMH is a very focused mini docu-series collaboration bw the 2 actors regarding LSG's personality and songs.

are similar in terms of themes of mental health, healing. similarities can be drawn amongst the characters: an angry, strong female lead in both
a caretaker in a mental health hospital in its okay
an eccentric psychiatrist in soul mechanic
both deal with social issues and mental health, both have romance as major themes and healing comes from both ends. similar in terms of how they make you feel.

not really similar in terms of concepts and settings, but both deal with addressing mental health and various social issues and healing from past traumas. mystic pop up does not have romance as a main genre and is more comedic and family friendly than its okay, but both are similar in terms of over arching themes and the feeling of healing they left me with.

a similar story of mystery and sci fi. repeat is more about time travel and a mystery related to that, whereas train is about travelling between universes. a similar dynamic between the main leads. similar serial murder mysteries, character dynamics and good story telling elements in both.

a similar food oriented romantic comedy
the main lead in DM is a therapist who treats people using "food therapy", and the female lead is PD who invites him on a show
