I would recommend that you watch 'Suits'.
Why you ask? It's one of the best dramas of 2018 yet or probably because of Park Hyung Shik ;D Not only his acting was top-notch but he's super handsome as well. The way he recited all the legal terms or definitions left me speechless. I don't why but I just loved everything about him, including his trainers. lol
Relationship between the main cast (Jang Dong Gun and Park Hyung Shik) or should I call it 'Bromance' was interesting to watch. There wasn't a dull moment in the show and each episode held some suspense that bound me to watch further.
I especially loved the quotes shown in the beginning of every episode hinting a little about it. My favorite one was "The best way to keep a secret is not telling anyone."

PS. People who are interested in law would definitely find it more appealing.
