You’d been the nanny for Riku and Yua for the past three years. You were 22 , the father of the kids, Woo-Seok was 33. His wife passed away 3 years ago, so he had been a single dad since You couldnt help but caught feelings for him which you never told him or made it obvious, as you took care of the 6 year ol Riku and 3 year old Yua he wasnt very much around only at night when the kids are sleeping.
