Se Kyeong Did Everything for her adopted mother so that she can be acknowledged as her daughter. Maybe at some point Se Kyeong thought that her daughter eun yu should also do same for her. Eun yu Should Reunite Her Grandfather and Her Mother. Maybe That will change her future without affecting others.
Future Se kyeong was like that because of her adopted mother and I think Eun You should focus on reuniting Her Mom and Her Real GrandFather AKA Eungyeol's Mentor.
This May Come In March 2024 .Because The Battle of Marriage Comes In October Last Week After That Fantasy Sonata Will Come.(P.S If it is a Monday, Tuesday Drama)
