This series doesn't have an amazing reputation but to be honest, i thought it was pretty good besides some unrealistic character attitudes. However, the last scene was unnecessary and completely ruined the entire storyline of the side couple. The writers were obviously intending to leave open an opportunity for season two. They wanted the last scene to be a transition into season two but if I'm being honest, i highly doubt there will be one. So now we're just left with a cliffhanger that came absolutely out of nowhere and gives us a shitty feeling about the side couple.
Despite this last scene, i really liked the series. I am probably not gonna rewatch it but it was really well made besides the things i mentioned above.
