Kaede didn't stop Mamoru from leaving and sempai didn't even notice. It wasn't until later when sempai had finished his magazine that he noticed that Mamoru wasn't there anymore. By that time Kaede was engrossed in his book. "Oh where did Mamoru go? Oh my it is already so late. Time to end club activities today." Kaede put the book away but not without noting at which page he had been. Time to go home. He said goodbye to sempai and went home for that day.
