Queen of Ambition charcter - Joo Da Hae is similar to Kang Seo Yeon both of them achieved their greeedy ambition but ended up in downfall. They have habitual lying and
threatening people by using their weaknesses which are their secrets. Both of them
ended up regretting their wrongdoings.

Both shows have strong female leads ( Run on definitely has the more realistic strong female)
In both shows, the leads have really good chemistry.
Both shows have dealt with the drama aspect pretty well where it's cliched enough that it's enjoyable.
Find me in your memory is more on the melodrama side.

Misaeng and Run On both about life. Im Si Wan is also the lead role. At Misaeng he is also an athlete who failed to become a professional go player and has to change his career. There's a lot of life lessons that you can jot down in that drama but you may found it kind of boring because there's not much music just a plain conversation as if you're observing an office life and how will Im Si Wan character will keep moving forward and keep moving up in his career. In Run On he failed to continue his first sports because of an injury then changed into a runner then retired as an athlete because of unpleasant incident. He'll learn to change career and keep moving on in his life.
Both drama teach a lesson about life, how to be a mature person.

this one isn't horror but the concept is very similar.
someone gets kidnapped for purpose to put up a show for rich people, being watched by cameras and streamed.

Also starring Moon Ga Yeong and her role is also a shy young woman with insecurities because she easily turn red.
It is also a Rom-Com genre with love triangle between 2 friends.
She also has a younger brother who always annoy her but love her hehe

Both are about two male leads and their strong bond (in reality it is a romantic relationship but has censorship). Both are wonderful stories about eternal love that lasts through much hardships and trials. Both semes are questionably evil (this is debatable for spoiler-y reasons) and both ukes are kind and good at heart. Both have a good amount of mystery, suffering, comedy, tragedy, (b)romance, and fantasy. If you really enjoyed H2A then you would absolutely love Heaven Official's Blessing (go and read the novel!).

The main leads are males.
Both involve a 'school' where the leads can learn to improve themselves.
Both involve a group of youths willing to save the world.
Both main leads do not have parents.

1) Both have a male as main lead
2) Both are adapted from novels
3) Both are historical dramas
4) Both have a sense of romance
5) Both contains heavy use of CGI
6) Both somehow involve saving the world.

Both are BL seies set behind the scenes of the BL industry. Very meta, right? They do approach the concept from very different angles though. Howevever, in both our MLs fall in love with someone the industry and fandoms tell them they can't be in a relationship with.

These two dramas for one have Suda Masaki acting in them. He's super good!
Next is these both have two guys investigating cases together, though one is a information business and the other involves the police.
And duh, bromance.

Both revolves around characters who are suffering and then proceed to find and explore a new chapter of their life. They both portray love in a pure and destined manner and I must say the romance genre is very strong too.

Both series involve traditional Japanese crafts, Kyoto Love Story with dessert and Mare with lacquerware, though it is more of a side story. The ML in Mare is also into dessert but more Western dessert, unlike the one is KLS. Both series tackle the hardships and passion they have for their respected crafts and both series involve the main couples becoming the successors of their traditional shops.

Thai BL series. The stories are very different, Love Poison relies more in comedy than drama, however both BL series take place in Northeastern Thailand and some or all characters speak Isan dialect.

Thai BL series. Same as in A Tale of Thousand Stars, part of the story in Oxygen takes place in countryside Thailand. After the death of one of the characters Tian/Gui move from Bangkok to a rural area and become teachers.

Thai BL series. In both, one of the main leads in the couple moves from Bangkok to Northeastern Thailand to escape from the city and meets the other lead. Both stories start after the death of a woman and the mystery/consequences surronding it. If you like green scenery and Isan dialect, you will like these 2,
