People gather at a split-level flat on a backstreet of Roppongi, Tokyo, men pay ¥20,000, women ¥1,000 and couples ¥5,000 apiece to spend the hours of midnight to 5 a.m. at a sex party. A moody Neet guy empties out his bank account for this night of pleasure, and a bespectacled college student who at first impresses as mousy and shy join the party. Presiding over this orgy are a jaded manager and bartender who explain and enforce three simple rules: Take showers prior to sex, use protection and respect the wishes of the women. Most dangerously, the Neet guy is falling quietly and hard for the student, who reveals herself as the horniest of all, while never quite breaking out of her shell.

horror elements
ghosts
shaman
curse
Both have supernatural elements and a policeman and shaman trying to break the curse.

Well,, It’s all about the leads become an interpreter…
I haven’t finished the series but I believe the attitude of them might be similar (as an interpreter and the professionalism shown)

Spoilers!! (kinda)
Story-wise these dramas aren't that similar, but Endless Sea reminds of Twelve Letters. The idea of two young people trying to change their parents' / grandparents' fate with a letter as the key seems similar. While Endless Sea is about a time loop where both leads end up on the same day several times, trying to break the loop; Twelve Letters features the characters from the present trying to connect to the leads from the past via a letterbox.
Twelve Letters is much more complex and heart-wrenching, and Endless Sea is a quick, easy watch.

Both feature:
- A romance between a celebrity and non celebrity
- The FL is the pursuer and attempts again and again to influence the ML

Differences:
- ML is the celebrity in Lovely Runner vs Female lead in Can This Love Be Translated
- In Lovely Runner, the 'groundhogs day', sci-fi element, of rerunning the scenario over and over helps justify the FL trying again and again despite getting shot down
- Lovely Runner has very satisfying romantic scenes for the audience once the two leads start realising what's going on and start connecting

Would highly recommend Lovely Runner!
