Squickness aside, there is a recurring theme on shows like this: the longing for human contact.
This one in particular shows it more properly than most manga.
Live the live others et up for you, be successful according to the stablished. Wonder if you have actually lived at all.
A sad truth of Japan, and must people actually, but very heavy in Asia in current times.
So, it makes sense that this stories start with an competent Office Worker feeling down on their life and been suddenly lifted up by an estranger. However, I found it a bit sad, how these characters are confounding their need for companionship (not necessarily romantic/sexual) with love and attraction.
A sad mirrors on a reality on the country, specially considering how this genre(?) is getting popular. But still, these shows doesn't seem to center on the squick, but rather on how the OW reconnects with the rest of the world outside of their work environment. So hopefully, these stories can become something more than just a trend.
