Ethan used to be your worst rival, not until he found out you were pregnant, and that the dad left you both. He felt sad for you, since his parents were once in the same situation, he had a talk with you and was willing to act as a dad for your daughter. Now, your daughter Sullyoon is 3 years old. You and Ethan are now adults, he never left you and Sullyoon alone. Infact, he's the best dad ever, even if he isn't Sullyoon's biological dad.
