I like story line.. but i dont think plot gone smoothly becoz i fell lot of missing parts.. in the first few episodes it is realky exiting but when come to the last few episodes i fell whole drama is dropping somehow i dont know why i feel like that.. but i am thnkfull tht rang is reborn otherwise my heart will hurt long time.. This drama has one thing that i want from every drama. That is in the end they show what will hapend to every single character. I teally love that kind of end ❤️❤️

As for acting they did thire job very well.but i fell somthing missing from yeon.. lee dong wook is good actor but somhow i fell somtimes in the drama he lost( not everytime just some scenes) it is somthing like i feel from lee min ho in LOTBS..
As for rang he did very good job and i love him. He manage to catch our heart than main lead. I even feel angry at him for sacrifice his life for yeon.. and i did not even cry when yeon die but i cried when rang sacrifice his life.
As for villans in dramas i dont think they are success.. becoz when villan apear we should fell tens but when lee tae ri come i did not feel tht.. he is good actor i think writer write his character like that. If he make calmly villan he should choos guy who has tought look... ( i dont tell tae ri bad actor somehow he is not suitable for this) and yes immogi in ji ah s body also fail. I think jo bo ha only success doing character ji ah not imoogi. She faild acting as imoogi..
And whole other actors did good job

Overall good itz ok to watch thire r lot things i did not feel ok but i must say i enjoy it somehow.. and it is not boring type drama.. i did not rreduced so much stars.. so i think you can watch it.. and i think lot of you put this drma to 2nd lead syndrome list ?
