He is truly a man of class, a 'daijoubu'.

I think his behavior is abnormal.

He missed school because of sickness.

Although he was tired, he continued to work.

Despite my opinion, he pushed through with his own thoughts.

He is a person who cares about every detail.

He has no involvement in the incident at all.

His actions have a deep connection to all of us.

He is always concerned about his health.

His actions are a matter of concern to all of us.
