I didn't expect this drama to be so moving I mean knowing that I watch the English version movie with my fave actor Zach Efron!! Can't help to compare both, 17 again movie which i loved so much and rewatching it again...This Korean version is what can i say!! They spiced it up!!! Adding more emotions and romance! Emotions was spot on!! Parent and children relationship is being a focus here, the cast was really act well and did amazing portrayal in their respective roles that it makes it so exciting to watch!!!A MUST WATCH!!!
