Seo Kang-joon's drama is just not interesting

‌They marketed it using Seo Kang-joon's visuals at the beginning,
but it's not that kind of drama at all.
It's a family drama.
There are so many backstories
and so many incidents.
And the drama itself is too difficult—I hope I'm using that expression correctly.
Looking at the combination of the director and writer,
it seems like they struggled to put this together after doing single episodes,
but it looks like it's going to be a tough one.
