I didn't know what the show was about when I jumped in except that the mom, Mi Hyun, had enhanced senses. I think the first 2 episodes really got me. I just love how cute Bong Seok and Hee Soo are together. That was my favourite part during the first part.
I loved Bongseok's character so much! I wish he had someone to teach him how to control his powers.
On another note, having watched Ryu Seong Ryong's (Heesoo's dad) previous movie Extreme Job, where he also opened a fried chicken shop and had the reputation of being "unkillable", I feel this series is like the continuation or prequel of that! Lol
