1x04 Episode 4

Some fun moments, some good but unbelievable action. However, too long and cheesy moments.

I am loving chemistry b/w Seung-woo and Shin-Hye ; its awkward and yet cute!!

For the first time time travel is explained well in a K-Drama with proper science
I don't get why Seo Jin would regret not helping Tae-sul ; she looked like she left him dead for good even before
