The result is: singapore

I don't know why the scalar $note_whom get the value that is assigned
to $otherthing.
Please give me the explaination, and thank you.
Because of precedence you have:
(defined($something) ? $note_whom = $something : $otherthing) = 'singapore';
You need to add parentheses:
defined($something) ? ($note_whom = $something) : ($otherthing = 'singapore');
