Drama recommendations with very rich cold male lead

• My Holo Love
• The Devil Judge
• Ghost Doctor
• Bulgasal: Immortal Souls
• My Liberation Notes

Secret love (With Ji Sung and Hwang Jeung Eum)

For a serious, melodramatic or thriller K-drama with a cold-hearted, rich male lead, "Secret Love" (also known as "Secret") and "My Love From the Star" are good options. "Secret Love" features a wealthy, cold-hearted man seeking revenge on the woman who was responsible for his fiance's death, while "My Love From the Star" has an alien who is aloof and detached due to his long life and hidden identity.

Despite its success, What's Wrong With Secretary Kim? is not free from criticism. As other people have said, it is a fluffy rom com so if you’re not into that you might not like it.  It's not for everyone. I like it! Love the lightness and romance. It is far from perfect.  I watched this for Park Seo Joon. His character is a hilarious narcissist. What’s Wrong with Secretary Kim is a cute drama that is worth watching and my favorite genre is rom-com. I did find it worth the watch and really enjoyed it for what it was! I personally think this is the hottest Park Seo Joon has ever looked in a drama and he was fun to watch in this role.     It is cheesy at times but it's fun and heartwarming. It's filled with tropes but it worked for me.
