The show debuted on December 18, 2013 and had an average viewership of 24% in Korea. It then sold to China where it's been viewed online through iQiyi, a Chinese video streaming platform, alone 14.5 billion times.
The premise is catchy: An alien lands 400 years ago in Korea and falls in love. Fast forward to present, he meets his first love's doppelgänger — a haughty starlet, and inevitably falls in love with her too.
The show has sparked all sorts of trends, namely one for chicken and beer as it's the heroine's favorite food combination.
Even China's A-list celebrities bought into the trend. Gao Yuan Yuan, a Chinese actress, posted this photo on her Instagram with the caption: "First snow. Where's my fried chicken and beer?"
In Jiangsu, an eastern Chinese province, a pregnant woman nearly suffered a miscarriage from binge watching the show late into the night and eating too much fried chicken.
In Chongqing, a major city in Southwest China, a woman supposedly dumped her boyfriend after he refused to buy her fried chicken in the middle of the night because he wasn't as romantic as the show's leading man.
Another story reported that a 50-year-old Chinese woman suffered a heart attack from late night binge-watching and getting too "emotional" over the storyline.
