I WATCHED IT becoz of reviews... but felt little disappointed with how the story went in the later part. It's about 3 friends died in past for freedom of Korea from japanese( ahhh but there was nothing actually happened in that perspective and have't seen any actual patriotic feeling specially from friend as he gave up his friendship and great cause ;main goal towards nation just for the sake of measly Love ahhh..) and two of them (main leads of course) reincarnated but the friend became ghost and captured in typewriter. They wrote novel together to regain their past memories..
Main male lead(se ju) is tolerable.. but female lead bothered me from the starting as every time i looked at her as a mom of je su. too old for him. chemistry was not that appealing sorry.
It could hv been far too better but every thing was predictable for me and nothing was surprising. Story was stretched unnecessarily.
Still it's one time watch if you have enough time.. Didn't want to harsh as they worked hard.
