Yoshiyuki Takamura

Yoshiyuki is Kōta's biological father who, after years of widowhood, entered into a new marriage with Misaki and formed a family of four. Warm-hearted and naturally optimistic, he places the harmony of his household above all else and holds deep affection for his wife and children. Yet he remains entirely unaware of the undercurrents stirring beneath the surface, never noticing the secret forbidden feelings quietly developing between Kōta and Aika.
