Personally, I started watching, since I had watched shows with both leads in before. Right off the foot I really liked this drama. It had this sense of realism that it dealt with well. All the serious issues through real-life were portrayed fantastically

I've heard some people say they like the second lead couple more than the main lead couple. In my opinion, both are amazing, but the lead couple is the lead couple for a reason.

It had a very satisfying ending that left me wanting more, but not needing more, as the satisfaction was enough

Would totally recommend it.

Shows like this:

The main male lead character is very similar to his character in Reply 1988. So if you like that, watch Reply

Another show that is very good, and portrays life issues, is Sassy Go Go, or rather, Cheer up. The main female lead from this show is also the second female lead in Cheer up.

Lastly, a very new drama would be Private lives, with the main male lead being the same as this show.
