There are many if you like melodrama: For action there is K2 W- two worlds Goblin Scarlet heart ryeo While you were sleeping Che if kim Cheese in the trap Healer
Forgot the title but hes a paranormal detective and a ghost follows him on his cases. Well technically hes a legit detective of police but he can perceive paranormal entities like seeing them or able to fight against them. Seen it on Thrill though
The drama about ghosts is called Hey Ghost Let's Fight, it's with Taecyeon ^^. Male audience I can only see City Hunter ^^. It's really targeted towards male sentiment, it's what got me into dramas. One of my favorites. Goblin, Descendants of The Sun, You Who Came From The Stars, the biggest blockbusters are targeted towards the largest audience but it still appeals the most to females, I'm a guy but I like watching the witty characters and stuff but I know some people won't enjoy it because it's too cheesy. Then, you might enjoy the stuff like Criminal Minds, or Signal. It's more targeted towards any people who like to think a little bit, no romance, just investigation and mindf*** ^^.
Healer (action and romance, suitable for both genders) History of the Salaryman (business, subtle romance, guy going from nothing to something, suitable for all audiences) Cruel City (crime, gangs, fits perfectly for male audiences) Six Flying Dragons (best kdrama historical, made for all audiences) A Gentleman's Dignity (best male humour drama, 10x more funnier if you are a guy, as jokes are more relate-able to them) Personal Taste (guy pretends to be gay) Queen In Hyun's Man (for a rom com surprisingly well suited for guys to enjoy too)
For K-Drama Fall that I am watching: While You Were Sleeping - I am just watching for Suzy Because This Is My First Life - (Female writer who went to the most prestigious uni in Korea quit her job and marries her Landlord - Marriage Contract. Landlord is a very numeric and a brillaint engineer/programmer) - The chemisty between casts is amazing. The best friends on both leads sides are making this drama. Witch's Court - (Law Drama, Female Prosecutor, that's very focus in winning cases) - I love the female lead, she is hilarious and so brilliant. Go Back Couple - (A newly divorced couple getting timewarped back in time, right before they met again) - I love Jang Nara.
