BL dramas. In both one of the leads (the one who comes from a lower social class than the other) makes a deal with the other lead's father to advance in his career, improve himself and make himself worthy of becoming a part of the family, in order for the father to accept their relationship. Both share complex Dad/Son/Son in law dynamics. The second couple is also similar with a cold guy/clingy guy dynamic.

Thai BL dramas. Both take place in both highschool/college with multiple couples and side characters. One of the leads has a special connection with a 'Frog prince' that is later revealed.

Thai BL dramas. In both, one of the leads has a mysterious chat friend (Guy from faculty nearby/Frog prince) who he confides his day to day life throughout the episodes and that is later revealed with a bit of a plot twist.

C-drama where FL works for the ML who is a CEO. They had a relationship in the past and they reconnect over the course of the episodes and fall back in love. Not as funny as What's Wrong with Secretary Kim.

Pan is met with a unlikely accident suddenly with one of her ship bl couples, Kim. She returns to earth, but not as herself. She returns as Kim.

- The genre is the same (romance);

- In both shows we see the concept of telepathy. In SJNJ, Sun is able to hear other people's thoughts indiscriminately, whilst in VITR Tanthai and Rarin can only hear each other's thoughts;

- Sun and Tanthai are two very similar characters. They consider their power to be more of a curse than something good and listen to music to isolate themselves. This is why people often think they are arrogant, impolite or simply bad people and, in turn, they try to avoid people as much as they can (besides their circle of close ones). In both cases it's love that will change them and make them a better person.

Very similar setting- Asian Empire theme, main female lead from a different nation, both are pretty and equally witty. Empress Ki is Korean, about a tribute/slave girl from Goryeo (now Korea) who disguises herself as a man and eventually falls in love with a king and the emperor and becomes empress. There is the same strong-willed, intelligent female leads coming up with solutions to problems while others try to trip them up. The cast in Empress Ki are also incredibly good-looking as they were in The Princess Weiyoung. In Empress Ki, I enjoyed the antagonist actress for Empress Tanashilli- she was great, very well-done performance and you sort of 'love to hate' her. I got the same impression from Touba Yu in The Princess Weiyoung. Weiyoung is similar in that Xin'er/Weiyoung is from Northern Liang and has to negate her way through court by avoiding tricks/mishaps/setups whilst also falling in love with the Emperor's grandson.

Birthcare Center has a more mature approach considering it's showing the life of mothers with newborn babies. Both dramas have great sismance vibes and showing females supporting each other. They have great comedy but also give meaningful messages. Actor Yoon Park played in both dramas.

Both dramas are based on novels by Priest and share the genres Adventure, Mystery and Wuxia. The stories have a couple similarities and both have a Playful Male Lead.

Similar story, both have pregnancy involved. The female lead gets pregnant after one night. She has the baby without the male lead's knowledge. They meet again years later.

Culture, palace, being “drafted” to work in place and make clothes. Mystery surrounding death of mother....smart female lead ....

Both are fantasy and are about hunting vengeful spirits and lingering ghosts.
Main leads have special power to see ghosts.

The story tells about weightloss of the female lead and how they rebound several times from thin to fat to thin again. It also shows many foods and the male lead is a chef. Everytime the female lead get fat, she hides until she can reach the ideal weight again before going to public.
