In the end, Mikito Hanzawa dared not disobey Kazuki.
The threat from Tanimoto Natsu's eyes was the secondary reason that caused Mikito Hanzawa to say those words. The main reason was that too many people were looking at him. He was not used to the attention he was getting. He could not put his ego aside, and he was ashamed. He could neither start attacking nor hit someone in front of so many people...
His personality had always been like this. He never liked to be watched by too many people. He would prefer to stay in a corner silently and be alone. He liked simple things, such as being able to smile with satisfaction when he got home and looked around the house. He also loved to watch anime characters, empathizing with the characters' lives.
