I LOVE this show. The chemistry between Song Kang and Han So-hee is unbelievable and both actors carry out their roles perfectly. I have watched MANY K-dramas and this one is one of a kind. It is so much more realistic and relatable. I have watched all of Song Kangs works, but none of them had me reeled in to him, as much as this one. (I even practiced drawing the butterfly he drew onto Nabis writst). Both the lead actors deserve a huge round of applause for being brave enough to take up such a daring role. I definitely encourage you to watch it (if you are 19+)!
