As many mentioned, this is a great show, realistic and very positive. The drama is well balanced with heartfelt moments.
What I enjoyed the most about this show is the great relationship skills displayed by the characters. You can witness efficient communication, where human do their best, try to own up their mistake, express their feeling and listen with an open mind to their counterpart. They manage conflicts and have real connections, which contrast greatly with most dysfunctional relationships displayed in most drama shows. Very enjoyable, I recommend this show.
