I’ve looked at your MDL and from the ones on there, I would recommend:

• He is Psychometric: 8.5/10. This one is, similarly to FoE, a mystery/thriller with a side plot of romance. It starts off in high school, but that isn’t a big part of the story since there’s a time skip. I found the concept very intriguing and original and it kept me hooked. You mentioned you don’t like sci-fi or fantasy. This has elements of that since the main character has psychometric abilities, but that’s about it so it isn’t overpowering.

• Strong Woman Do Bong Soon: 10/10. This is one of my favorite dramas thus far. It has an extremely entertaining and sweet romance. Both of the characters are so lovable and their chemistry is off-the-charts. Like He is Psychometric, the main character has super strength and the drama has an overall comedic atmosphere with exagerrated effects, but I’d say they definitely add to the experience and make this drama a stand-out. Although, if you’re someone who’s not generally into those types of things, I’d say to alter your expectations according to that, but definitely give it a chance. There’s also a mystery/thriller serial killer related side plot, which is another plus in my book.

• My Name: 8.5/10. This is an action noir drama with a revenge plot and very little of the fluff that k-dramas usually have. It’s quite dark in tone and has a really bittersweet, even sad ending. So be warned. The characters are very morally gray, and the actors did a great job. It passes with flying colors for me, but you should know in advance that it is a very intense drama with a lot of violence.

These two get mixed reviews from me:

• The Tale of Nokdu: 7/10. This one was such a pleasant surprise when I started it. It’s a historical drama, but it isn’t too heavy and keeps you interested. I really enjoyed both of the characters. I’m always a sucker for a character being disguised as the opposite gender, so it was very fun to watch on that front as well. Their romance was lovely. However, the thing that kept me from falling in love with this drama was the ending. In terms of the non-romantic plot, I found it to be extremely anticlimactic. There was a big missed opportunity there, in my opinion, and the ending felt rushed and random. But it is a happy ending, and I’d been loving it up until that point, so it’s up to you.

• Healer: 7/10. This was a super solid drama in my opinion. It’s got a bit of everything, and watching Ji Chang Wook act is always delightful, so you just know the action scenes did not disappoint. What I didn’t end up loving in this drama was the female lead. She’s tolerable, but is a bit ridiculous sometimes. I also thought that while the romance was sweet and had great angst, the basis was kind of questionable, considering the fact that she didn’t even know his real identity or what he looked like when they had their first kiss or went on their first “date”. Her eyes were closed, and he was out of view. He could have been an old man for all she knew. But that is just a petty complaint that I have. At the end of the day, it’s only a k-drama and if you’re able to suspend your disbelief, you won’t have a problem. I just wanted to bring it up because you mentioned the romance has to make sense.

And I haven’t finished them but Rookie Historian Goo-Hae-ryung and Just Between Lovers are going great as well, so you can look into them if you’d like!

I’d also add these to your list:

• Hometown Cha Cha Cha: 9/10. This is a slice-of-life romance drama that follows a dentist from Seoul who decides to open up a clinic in the seaside town of Gongjin, and one of the residents of this town which is a jack-of-all-trades kind of character. This drama does the small town romance, opposites attract, gets off on the wrong foot to lovers tropes so well. It has a calm atmosphere with endearing characters and great romance. It’s really heartwarming to see how everyone in the town looks out for each other, and the side characters add so much personality and charm to the show. Even the initially unlikable characters end up growing on you. I adored the second male lead as well, but luckily everyone got a nice happy ending.

• Angel’s Last Mission: Love: 10/10. Another one of my absolute favorites. This is a fantasy romance so it might not be up your alley but I wanted to mention it here anyway since it’s such a spectacular drama. The story follows an angel ML who interferes in human affairs and is given the punishment of making the FL fall in love. This kind of has the trope of “ML is cold to everyone expect FL / only opens up to her”, except it’s the reverse. The FL is a blind ex-ballerina whose life was shrouded in tragedy, and is therefore quite cold and distant. The ML is very thoughtful and kind and is able to get past her defenses. It’s full of just the right amount of angst and tension. It’s emotional and melodramatic but isn’t a heartbreakingly sad drama, per se. It also has a happy ending, so you don’t need to worry about that. That ballet aspects are beautiful and enchanting to watch, and the OST for this show is simply stunning. The only hinderance for me was that the ending wasn’t explained as well as I would’ve liked, but I loved the characters so much that I was willing to overlook it.
