I love this movie but the ending ticked me off. I like how she met him again as a grandmother but I personally think that they should've met earlier and gotten together rather than Sunyi turning old and marrying someone else. Although the Cheolsu could end up with Sunyi's grand daughter, i still feel like the connection between them wouldn't be as strong since she's not Sunyi herself and doesn't share the same past even though they share the same face. Not sure if im the only one who thinks this way but love the casting! Both my favourite actors :)
