story was going well and then they dropped that childhood connection around ep 24/25. her father is the reason or smth his father died . i mean based on these C/K/J dramas u will never find love if are not connected somehow from your early young days. kdrama does this way too much though.
based on experience watching k-dramas it seems likely that seo ji-u's driver is actually her father. i mean he’s old enough to be her father, was always with her and now he's back.
so lin and ji experienced parallel timeline but cant believe her father also experiencing the same but in future for him. weird innit? (ep11 continuning....)
