Anyone can recommend me some complete ones from this current year? Because all the time-travel ones from before I’ve watched them all already, trying to find the latest ones with a strong and optimistic FL and a historical romance time-travelling one with at least a love triangle if not a full reverse harem too is fine with me. I want a time travelling historical romance drama filled with handsome, cute and sexy MLs in ancient Asian costumes. Now, I don’t care if it’s reincarnation time-travel or how the FL time travels, but it has to be to an ancient past like a few hundred years ago. And with her modern smarts, optimistic attitude on life and her lacking regards to pre-established rules from the dynasty, she makes every noble men or princes or the emperor himself swoon over her and fall head over heals in love with her and will do anything to win her heart.

The Romance of Tiger and Rose - This one is a recent Cdrama and it finished airing a few days ago. The plot is a little unique but definitely ticks off most of the categories you have mentioned above :D .

I second The Romance of Tiger and Rose but (as of today) subs are only up until ep #22.  If you enjoyed ZLS in Love Better Than Immortality, she's better in this.  Still cute but not as annoying...

As for 2020 titles, these are on my to-watch-next list after TROTAR that also look like the same theme you've a hankering for: Love and the Emperor, My Fantastic Mrs. Right

I've found that c-dramas have been hot on this since lots of current Chinese readers like these isekai-style stories.  Lucky us!  How have you NOT watched The Eternal Love yet?!?! I know it's not a 2020 release but it's a must watch for everything you want, even if she doesn't have everyone loving her cuz she's such a brat, haha. It starts off with her waking up in the parallel universe & proceeds with a well-paced storyline into sheer fantasy.  The MC's chemistry is GREAT.  It's even got a Season 2 where they start  in the present-day and she returns to the parallel world.  It is the drama that hooked me on these types of stories so I highly recommend it. :D

Based on your list, I would recommend these similar story lines from the last couple of years. (Both are romances with a lot of comedy.)

1.) Oh! My Emperor (more ZLS but cutesy-ish, so not as mature)

 Naiwen:
handsome, cute and sexy MLs in ancient Asian costumes

And oh-my-my-my does it have this in SPADES. She has the entire boy band XNINE at her disposal. ;)

2.) Unique Lady (here, it's a "video game" past version of the world she enters in to discover love)

 Naiwen:
modern smarts, optimistic attitude on life

She's pretty funny, too. Our ML (Simon Gong) is the perfect childish bully-turned-yandere in this but she has many other attractive men in costume since she's meant to choose between them.

I would love someone to start an isekai-style c drama recommendation list, actually! :)

I don't care for English Subs as I'm a mixed native Asian female and understand most Asian and Western languages, including Hindi, Arabic, Sanskrit, Tibetan, Mongolian, Chinese Mandarin, Japanese and Korean. I watch them all in their original languages and have watched everything on your list. "Oh my Emperor" and "Love better than Immortality" being my favorites from Zhao Lu Si. I'm watching "The Romance of the Tiger and Rose" raw currently and I'd love a few more to binge during the pandemic which makes it easier during the lock down in my area, thanks a lot for your help, guys. I love Tiger and Rose, btw! I'm on episode 3 and love the ML and SML so far, exactly what I'm looking for, thanks for your help! Anymore please?

Please don't recommend me the ones from before 2020, I have watched them all and read before recommending, I want the latest ones from this year! Not the ones before 2020!

Repeat the Year 365 kdrama
