If Suzy's character is the only thing putting you off,I suggest you watch the episodes aired till now and then decide.She is quirky but you might not find her annoying. Give it a try since the plot & pace is good right now.

You spoke my mind.I love Lee Jong Suk.Loved him in I Hear Your Voice but even he couldn't make me rate this show high.The romance was just not convincing.The plot seemed contrived and it felt like events were happening without any head or tail(or maybe I am just too stupid to understand) just to move the story forward conveniently. Had it not been for LJS,I would have probably dropped the show in the middle.Yoon Joo's characters annoyed me tbh.Her constant crying irked me.He love for a cartoon character bewildered me.She was pining away for Chul even after he shot her father.Like how?! There were no clear rules to travel between worlds.It kept changing conveniently.The plot had so much potential which was left unutilised. Good dramas leave you wanting for more. but that was not the case here.Even cliches or mediocre stories can leave you with that feeling if told convincingly enough,if written well enough.
