What does this person mean by "doryo" in this context? Two Japanese-fluent characters in an English novel I'm reading are talking about a specific heart problem one character concealed from medical exams. That character is requesting the second character keep this secret, lest they be kicked off the mission. The second character drops briefly into Japanese: > "Watakushi no doryo wa, wakarimasu," Nicole said kindly, changing into Japanese to show sympathy for her colleague's anguish. Both characters are fluent, and I believe the writer was as well. One of the problems here is whether "doryo" should be written or - this would help with translation. However, none of the translation services I've tried actually seem to translate this in any way which makes sense. The closest I've gotten from Google has been "magnanimity" - but I don't think this makes contextual sense. What is the meaning of this statement, and how should "doryo" be written in hiragana?

It is likely `[]{}` which means "colleague"/"coworker".
