After divorcing Pasha Ungu, Okie Agustina married footballer Gunawan Dwi Cahyo. Coincidentally, the three children from her marriage with Pasha also lived with Okie, which automatically meant they lived with Gunawan. The closeness between Gunawan and Okie and Pasha's children is extraordinary, making them feel like biological father and children.
This is evidence of the closeness between Gunawan and his two daughters, who are very close. Father and children feel like friends!
