Do-yoon is about to leave the orphanage when he legally becomes an adult. Instead, he is reunited with his father Seung-won, who appears after 15 years to take him home. Do-yoon adjusts to the newfound family that also includes Jae-min, a little brother. Seung-won’s sudden death makes Do-yoon the legal guardian, and he comes across something strange in his late father’s records while trying to claim insurance money. More shocking evidence is found at the orphanage, and Do-yoon feels all the more confused about his identity as he gets nearer to the truth. (Source : pipff.org/eng)
