Based on the novel The Lekki Headmaster, why does Mr Bepo yell "Noooo!" during the drama club performance at the farewell celebration?

This question asks about the reason behind Mr Bepo's emotional outburst during the drama club performance at his farewell celebration.

Mr Bepo yells "Noooo!" because the drama club's performance triggers powerful memories of his visit to the Heritage Slave Museum (the Black Heritage Museum). The performance likely depicts scenes related to slavery or the suffering of Africans, and these images bring back the deep emotional impact of what Mr Bepo saw and felt during his earlier visit to the museum. The overwhelming rush of those painful memories causes him to cry out involuntarily.

His reaction is not one of disappointment with the quality of the performance, a feeling that the students are being disrespectful, or a disagreement with how history is portrayed. It is a visceral, emotional response rooted in his personal connection to the history of slavery, which the performance vividly brings back to the surface.
