I love Park Min Young, she is one of my favourite actresses. When i found out that Song Kang (i only saw him i. Sweet Home) was the main lead i wasn't sure about their chemistry, but after a couple of episode I was surprised that their chemistry actually worked. As everyone said FLAW started really good but in the middle something happen, it was laking and so much useless drama between the leads. I don't hate HKJ (at first he was a total jerk) but some people in real life can have a friendly relationship with exes when they don't have any feelings about the other part (no hate, no resentment, no romantic emotions, and the fault is in between the 2 parts (btw i am not justifying the cheating)) friendship can happen. I liked the story at the forecast station, i just had no emotion between the leads. I don't hated the show it was okay.
