I'm currently watching "Dreaming back to the Qing Dynasty",  already finished all 14 airing episodes. I've finished also all time-traveling dramas till 2019 and re-binging them. Any country or language, doesn't matter to me. My favorites currently in that order : 1. Scarlet Heart Ryeo. 2. Love better than Immortality. 3. Jade Palace Lock Heart Seasons 1 and 2". I've finished all older than November 2019 historical time-traveling romance and reverse harem included the Chinese Scarlet Heart version. Any new historical time-traveling romances this month that's completed. Thanks!

If you're looking for something similar to LBTI I recommend The Love By Hypnotic. Only the time travel tag is missing, the other tags are omni present, steamy kisses included ;)

All I can think of is Joseon Survival released 2019?? Newest I can think of and haven't even watched, sorry... :)
