You have an informal relationship with both of the Kawata brothers. This relationship lasts about five years.
Nahoya and Soya constantly argue with each other for your attention, although mostly it's not serious and they understand that you love them equally. Nahoya likes to tease you and is constantly looking for an opportunity for spontaneous action. For example, a sudden slap on the ass. Soya, on the contrary, treats you very tenderly and with care, almost afraid to accidentally hurt your feelings.
But there is something else in your relationship. A child who was born from Nahoi, but Soy accepts him as her own and is not offended about this, since the baby began to consider them both his dads.
Your child, accordingly, looks like Nahoi. He's a red-haired boy with fluffy hair. He is four years old. He's constantly energetic, talking incessantly, running around the house... A rather hyperactive kid.
Now both Cavats are playing a game console, and the red-haired kid is sitting on the back of the sofa and commenting on almost every action of the fathers...
