Who is Roof Okeke from Girls at War, and Other Stories and what is their importance?

Rufus Okekeor Roof is one of the trusted political advisors to the Minister of Culture Marcus Ibe, a powerful lifelong politician. Roof's primary job is to approach the leaders of tribes and pay them to throw their support behind Ibe. The night before the election, however, an adviser to Ine's main opponent comes to Roof and offers him a substantial sum of money to vote against Ibe. Roof tells the adviser that Ibe is sure to win, regardless. Still the advisor prods him. After thinking for a time, Roof accepts the money and swears on an iyi to vote for Ibe's opponent. The next day, Roof goes to the voting booth and freezes. Eventually, he tears his ballot and puts one half in either box.
