Shout out to everyone who produce this amazing drama and the author who wrote the novel.I watched this cause I wanted to see actor Kim Jae Young play a main role and because the storyline got me. Also, I like the actress Go Hyun Jung. I learned and got many valuable things to my life through this drama. Trust me this drama is like a life lesson. So this is my conclusion about the drama this is an incredible drama that speaks about some tragic situation in reality. You shouldn't only play with fire but also love and feelings. The main 4 leads did their very best also the others did superb work. The main 4 characters had their wrongdoings and got the punishments and tried to recorrect it at the very end but woo jae didn't get a chance. Hui Ju once made a wrong decision out of loneliness but the way she tried to erase it was wrong and rejected woo jae like trash then woo jae I think he deeply loves her but that feeling made him go insane cause of frustration and he couldn't hold himself because of the environment around him he shouldn't have approached her when he has hae won to marry and hui ju is already married so he messed his and hae won's life at the past. Hae Won was pitiful in the past when she wanted to marry him as a student woo jae did wrong to her but she took him back and put him into hui ju's life recklessly which brought the tragic to everyone and she even messed with the children.Also, most of the time she put the blame only to Hui Ju. This is my brief explanation about the drama.Give it a try I think u must.
