What is the main conflict of "Marriage Is a Private Affair"?

The
primary conflict concerns Nnaemeka's struggle against his father's will and the traditional Igbo
marriage custom, which prohibits him from marrying the love of his life, Nene. Nnaemeka embraces
the modern concept of love and willingly disobeys the traditional Igbo marriage custom by
proposing to Nene without his father's consent. Nnaemeka foregoes the traditional Igbo marriage
custom, which requires his father to choose his bride. Nnaemeka's father, Okeke, is portrayed as
a staunch traditionalist and arrogant man, who disowns his son after he discovers that Nnaemeka
has married Nene. For many years, Okeke refuses to acknowledge his son's marriage and shuns him
for life. Nnaemeka's decision to marry Nene is initially met with skepticism, but the Igbo
members living in Lagos eventually accept them. Despite Okeke's proud demeanor and refusal to
acknowledge his son's marriage, he receives a letter from Nene regarding his grandchildren and
begins to entertain the idea of making amends with his son.
