8.25/10 for #kDrama #YouAndEverythingElse - I started it because the synopsis reminded me of the outstanding #twDrama #ImperfecttUs and from beginning to end, this one suffered in comparison. For example, The concept expressed in the screenshot was better delivered by #ImperfectUs , which used quantum physics as a source of analogies and allusions. BUT the performances of the 2 leads in the #kDrama were so great they kept me going to the overlong, slightly mawkish end. The score is for them
