Finished Because This Is My First Life and I think it was pretty nice. The ending had me rolling my eyes again (with suddenly his old girlfriend showing up), but at least it wasn't as crazy as all the unbelievable connections in Her Private Life.
I will check out One Spring Night next, I guess.
One thing that made me wonder is ... do really all the houses have electronic locks / keypads or is that just a movie thing? Going by what I see in the shows, it feels like South Korea is like 30 years ahead of Germany when it comes to technology.
