Both are about childhood friends turned lovers but that about where the similaries end, thankfully. If i didnt enjoy Tonhon Chonlatee because of the script i highly recommend this one!
Lovely Writer is a great example on how to do BL dramas RIGHT and shows you how awful certain BL's and the industry are while still being a lighthearted cute drama

The exchanging part is quite similar to this drama ' she is the one' . But in that drama the elder sister had an accident that's why they younger one changed her identity into her elder sister to help her. I haven't watched this yet so i won't comment abt this drama. I hope this review may help you.

Both films deal with great sensitivity about sistherhood, growth and loss.
They have different histories, but similar messages.

Similarities
-in the brightest star in the sky the Fl is the assistant of the Ml in the entertainment biz
-in ugly beauty the Ml is the assistant to the Fl in the entertainment biz
-in both the Fl liked the Sml first
-in both the Ml has ptsd with a fear of fire

Both of them are Republican era dramas ,, Both have amazing Bromance or Brotherhood relationship ,, Both have the same painful stories of this era fighting the corruption ,, a lot of killing and action scenes in both dramas
Both you will feel how strong relationships can be formed without having it to be blood related or romantic aspects
I loved Both dramas so much

Similar in term of obsession , where the ML becomes a stalker , it very good but be aware of some nudity

Similar story line.
In Lucky romance, FL need to sleep with the man whose zodiac sign is tiger (ML) to break her bad luck and save her sister.

The protagonists are "forced" to live together for a certain period of time.
Supernatural ML
The FL have a death due date

The storyline about revenge is almost the same. The young princess (FL) also want to get revenge for her family and the ML loves and helps her.

The work environment is similar. They have to work together. One is liked by everyone. very funny.
-All characters are loveable
-Has comedy but can also get emotional
-No toxicity
-Great acting from main leads
-Great opening and ending song
-High re-watch value

Be Loved in House: I do and We Best Love: Fighting Mr. 2nd are both dramas which belong to the same genre: Boys Love. Also, both dramas are made and the stories are set in Taiwan.

Be Loved in House: I do and We Best Love: No. 1 for You are both dramas which belong to the same genre: Boys Love. Also, both dramas are made and the stories are set in Taiwan.

similar because :
- a moment with a special person is enough to change a life
- story love in a different country than them country of birth (Thailand)
- infidelity matter
- and good acting, original scenario but is rating too low by MDL !!!

A big city guy goes live in the countryside and suppost to help the villagers, the same goes with Going Rural, Osozaki is more dramatic and is an youth drama though!

1. Both have Secretary × Boss romance

2. Both have reallyyyyy amazing chemistry D:

3. Both are obviously Office romcoms. <3

Tho the plots are a little different, in the sense of romance and jobs and present connection of the characters it's the same.
You really need to try out What's Wrong With Secretary Kim if you're loving Oh My Boss so far ;)
