I know I’m late in that I just watched this show (in 2021) when it came out in 2018. This drama is pretty good but there are some things that I don’t really like about it.

Watch because:
-So Ji Sub. He really carried the show. He was very charming and manly.
-There are funny elements in the show that made me lol. Some parts are cute!
-The supporting cast is supportive of the female lead. No backstabbing from the best buddies. Best buddies were the stuff of dreams - supportive, helpful, funny.
-This drama is not too heavy in that it doesn’t leave the viewer feeling troubled, disturbed and perhaps, even frightened.
-There is suspense in the show and the show is quite fast-paced.
-Happy ending!

The stuff that I didn’t like:
-The female lead could be a different actress. I don’t think she fully suited the role. I don’t think she did a very good job.
-The female lead didn’t seem like a very good mother in the show.
-The two kids could be different too. They weren’t cute. They were annoying and I cringed whenever they appeared.
-Some parts of the plot weren’t well-linked / didn’t make full sense. (But well, drama is drama.)

Overall, this show is watchable. It’s just 32 episodes at half hour each or 16 episodes at one hour each. It’s much better than a lot of rubbish that’s out there. If you are searching for a drama and don’t mind an ‘old’ drama while waiting for this year’s releases, you can try this drama.
