If you are a fan of sun oh and jojo don't watch since you will be heartbroken.
First season is so bad that it's incomplete., no closure to all the mystery , trauma and everything. everybody is waiting for the 2nd season and when i watch it. lol! it's just a waste of time. Jojo not being true to her feelings as if she just push herself to Hye-Young. no healing to all the trauma experiences of the character except for Cheon Duk Goo.
after watching it, instead of feeling good, i feel PAIN. lol! WORST story so far. in fairness with the actor and actress they did good.
