Can you guys recommend any c-dramas with jealous/possessive male leads? It can also be dramas with leads who are absolutely whipped or in love with the FL.

I prefer watching modern dramas and I'm okay with borderline toxic leads, as long as there is no cheating included in their relationship.

I loved "Professional Single" and I'm hoping to watch dramas with similar concepts about jealousy, thank you!

Sealed with a Kiss. ( Verry possessive, toxic abusive ML) Hawick Lau is dreamy and nailed this character. FL here is a bit disappointing,I didn't like her look. I didn't think they had chemistry but Hawick Lau was so good, its worth watching.

The Confidence/ Unexpected falling - these are two separate dramas but with same leads and many same actors, also same director and there is reference to The confidence in the Unexpected Falling, so it does feel like a sequel. The ML, Actor Peng Guan Ying is absolutely hot and sexy. He plays the same toxic possesive guy in both dramas,there is bit more romance in The Unexpected Falling. The FL is so pretty and very good chemistry between the leads. Happy Ending in the second drama.

Modern c-dramas with jealous and possessive leads like in Professional Single...

  • Confess Your Love: definitely has the possessive ML who kind of manipulates things to get the FL to stay with him, acts jealous and territorial around her
  • Well-Intended Love: the epitome of possessive obsessed ML. This one is quite toxic and I personally didn't like it but if you enjoy the borderline stalker kind of obsessed ML this definitely fits. 
  • Love Is Sweet: more on the cute side, but ML falls first and is whipped for sure. He gets really jealous whenever she's around the SML.
  • Moonlight: watching this right now. ML falls first and is clingy, jealous, totally whipped, always trying to help the FL behind the scenes and keep her attention on him. 
  • Maid's Revenge: always recommend this one for possessive MLs. He is so hot about it too, WOW. Also completely whipped, the FL straight up stabs him and yet he forgives her instantly and keeps chasing her haha. Circle of Love is a similar one

I too loved Professional Single! Such a good drama. And the jealousy trope is one of my favs. 

Assistant of Superstar- I will never stop recommending this drama. If you're looking for possessive here you go. But it's in a super cute way. When I say possessive for this drama it's not toxic at all. Very much similar to "Professional Single and Moonlight. He's very whipped for the FL.

Moonlight- +1  This drama is basically "Assistant of Superstars" twin. The MLs are exactly alike I tell ya. He is possessive in the fact that he doesn't want her to leave, always trying to get her to come to him. And yes, he's a jealous man. But in a cute way! 

Once We Get Married- The leads get into a contract relationship, and pretty soon the ML falls for her. But he's not the only one. He's got a rival. The FLs childhood friend....  Ya, this ones cute. I love how the ML is always trying to prove that he's better. Such a fun watch.

Meteor Garden- Definitely on the more possessive side for sure. The ML is what I would describe a "bully." And he practically falls for her at first sight. Throughout the show he's all about showing how the FL is HIS, and HIS ONLY. There's misunderstandings and breakups, buttttt if you want a jealous and possessive ML, here you go.

My Secret Romance- Lots of jealousy from the ML. He's pretty possessive of her, and tries to get her back.

Yes, Assistant of Superstar is a great one! I forgot about that one. The ML is so clingy haha

I love this... Following for more recs
