I love the cocept i know soul swap is an old concept but the way they changed BL story into bromance it was good. The real and raw emotions of yi heon (gangster) who is educating others as well as sending them into right path at life was soo adorable especially with "bill man" and se kyung life changed a lot after they meet him. I love the plot and story too. At last yi heon was happy with gangster and left, it was so heart touching but old yi heon was so tried of this world and went. Then gangster got his dream come true with se kyung. I love the ending too, hope they make season 2 for this wonderful series.
