First of all, I believe if you are under 24, you might not be interested in these types of dramas. Even I wouldn't have been. But now I'm 25 and having second thoughts about my "peaceful" relationship, which isn't giving me much peace cus Maybe my standards have changed with time. And guess what? The second part ( 29), really hit me hard. It didn't offer any solutions, but it did bring a sense of peace to my mind.

The episode about age 42 was also nice, though I don't have much interest in the other two stories; I just watched them. All these stories were quite different from what we usually see in K-dramas. So yeah, just give it a shot.
