Only watched ep 1 of the season, is it okay if I skip it and watch this one?
No you have to watch season 1 first because season 2 will have flashback to what happened to that scene and so on. And you don't know what's going on with these characters and some characters died from season 1. I suggest you to finish season 1 first.
1. So K killed Dami, why? I forgot who killed Da Mi in the first season.2. who is Da Mi's biological dad? do we…
That girl's real dad is Kang Ki Tak, I suspected because it haven't been revealed, but I know that Ki-tak and Ra-hee were in love before she abandoned her own child on the bridge.
K & GRH's fighting scene reminds me of Penthouse S3 Joo Dan-tae & Cheon Seo-jin 's fighting while Logan & SSR were watching. π Am I the only one who thinks that?
Maybe you can wait until all the episodes release.
