how was Nnaemeka's father introduced in the story?

Nnaemeka's father is introduced at the very beginning of the story. He doesn't seem to be very understanding or empathetic to his son's choice for marriage.

“Have you written to your dad yet?” asked Nene1 one afternoon as she sat with Nnaemeka in her room at 16 Kasanga Street, Lagos. “ No. I’ve been thinking about it. I think it’s better to tell him when I get home on leave!” “But why? Your leave is such a long way off yet—six whole weeks. He should be let into our happiness now.” Nnaemeka was silent for a while, and then began very slowly as if he groped for his words: “I wish I were sure it would be happiness to him.”
