Beautiful Mind is one of my favourite kdramas. I love Jang Hyuk's acting. ❤

I have already thought about watching Faith because of Lee Min Ho and I didn't know other 2 dramas on your list.  Thank you very much 

Awesome!!!! You're welcome: D

I second Evasive Inquiry Agency and I also highly recommend Capital Scandal, Lucifer, Painter of the Wind and Liar Game (the Korean version).  If you liked Empress Ki (and have time on your hands) I also highly recommend Queen Seondeok and Six Flying Dragons - they  aren't "underrated" but they're great historical dramas.

Duel, Matrimonial Chaos, Confession , Revolutionary Love

Also The Great Seducer was popular but it got many undeserved opinions about it being poorly made. I really enjoyed watching it.

I liked The Great Seducer despite low ratings.  Woo Do Hwan is so handsome and I liked his character. It was really addicting and I love the OST. 

Thank you for your recs❤

I also recommend giving Chinese dramas a try! 

Shorter ones I liked:

  • Accidentally in Love
  • My Mr. Mermaid
  • A Love So Beautiful

Longer ones:

  • Meteor Garden
  • Ashes of Love
  • Eternal Love (Ten Miles of Peach Blossoms)
  • The Eternal Love
  • The Story of Yanxi Palace
  • The Prince of Lan Ling
  • Scarlet Heart
  • Legend of Fu Yao

  •  HoGoo's Love

Thai:

  • Bpoop Phaeh Saniwaat

If you rather watch short dramas, then japanese ones can be good option. They are usually 12 or less episodes long and many are underrated (< 8).

Attention Please - if you like comedy, aviation, Ueto Aya and personality of Misaka Youko. Otherwise you will go insane of her.

Goog Luck!! - another aviation drama, but now it is normal romance.

Miss Pilot - how to become pilot as a woman.

Tokyo Airport - last profession from Haneda airport - control tower :)

Limit - good psychological drama

Yuusha Yoshihiko - parody for RPG players

Battle of Changsha - Battle of Changsha retells the turbulent events of the second Sino-Japanese War from the perspective of the Hu family, particularly through the eyes of a 16-year-old girl named Xiang Xiang and her twin brother, Xiao Man. Gu Qing Ming is a strict Intelligence Officer in the Nationalist Army from a prominent political family. The feisty fun-loving Xiang Xiang and the arrogant Gu Qing Ming start off on bad terms, however, their romance blossoms as they constantly bump into each other.

Kairos - Living a precarious life as a part-timer at a convenience store, Ae Ri strives to support her mother who is on a waiting list for a heart transplant. Unfortunately, her mother’s worsened physical condition leads her to forgo the long-awaited opportunity for the transplant, and just like that her mother disappears. Things were already chaotic enough for Ae Ri when she receives a phone call from a strange man claiming to be from the same world but 31 days in the future. Ironically, he desperately asks Ae Ri for help. Seo Jin, a father and a husband of a close-knit family, has been living a successful life as the youngest person to become a director at a construction company. One day, it all crumbles down with the kidnapping of his daughter and his wife’s suicide. On the verge of breaking down, he is given an opportunity to restore everything that was lost under one condition, help from a strange woman. To bring his daughter and wife back to life, he makes a phone call as the clock strikes 10:33.

Legend of Hua Mulan - A retelling of the story of the strong willed Hua Mulan, who ends up joining an all male army in place of her elderly father.

Perfume - Seo Yi Do is a top designer. Although he appears to be the perfect man on the outside, his personality leaves something to be desired. On top of that, he has about 52 phobias and 35 allergies. Min Jae Hee is a middle-aged housewife, who has devoted her life to her family only to see it fall apart before her eyes. She discovers a miracle perfume that makes her look young again. After recovering her youth, she ends up walking the runway in one of Seo Yi Do’s fashion shows and signs with a top modeling agency to become a celebrity. Both of them get a second chance at romance in what is described as a fantasy romantic comedy.
