Kaede had not greeted Mamoru basically because he had wanted to give him another chance to be nice to him, this obviously failed as he didn't get greeted. Now Kaede doesn't want to make their relationship any better either. When sempai came in and greeted them, Kaede wanted to greet him back but before he could do so Mamoru cutted in. The jerk was totally doing that on purpose. He decided to just focus on the book instead of giving Mamoru the pleasure of his attention.<br/><br/>Sempai was completely obvious to the situation and chatted with Mamoru. He had to admit having lost/forgotten the magazine somewhere. He apologized even though this kind of behaviour was kind of typical for him.
