Romcom crack with a lot of heart. Best in the genre since 'Crash Landing on You' (albeit 'The Story of Park's Marriage Contract' is a close runner-up for me this year). The drama suffered in two areas - 1. it was too long (as with most KDramas - 12 eps would've been sufficient. 2. Dull villains, adding very little to the story. Yoon Eun-sung could've been a potentially interesting character - but it seemed the script and direction had very little interest in fleshing him out narratively. Also Park Sung-hoon (who has impressed in previous antagonist roles e.g. 'The Glory') seemed uninspired here. But the core of the story — appreciating the people that matter in our lives & redeeming failed relationships (both in love and within family) — was there all throughout. It was heartfelt, funny, dark at times, and sincere. PD Kim Hee Won was amazing as always. I've been a fan since her 'Money Flower' days, and it seems there's no genre she can't direct. And the cast - from the leads to supporting roles were all stellar. I loved Kim Ji-won in 'My Liberation Notes' so its awesome to see her in a hit role, and Kim Soo-hyun was amazing as well. Overall, 8/10 for me.
