Ueno tries to engineer a reconciliation between Ishida and Kazuiki Shimada, who was Ishida's best friend in elementary school, but threw him under the bus.
This fails.
Ueno blames Shoko for... roughly everything. She pulls her aside and suggests a peace treaty.
As two people who hate each other, can the just agree to coexist?
But Ueno's assumption is wrong. Shoko doesn't hate her.
Shoko hates herself.
Yuzuru has secretly videotaped the conversation and shows it to Ishida.
He says he wants Shoko to like herself.
