rewatched this drama far too many times in 2021 still cant get over how amazing it is and the chemistry between the two leads (kim soo hyun and seo yea ji) and if your reading the reviews to decide if worth the watch? YES! its worth it if you have a watchlist to binge watch i suggest you drop them and watch this first as it will show you what true acting, psychology, romance, drama and alot more this show got all the genre from murder mystery to romance i relly hope this help people to decide if this is worth the watch thanks!
