How would you describe a mysterious person?

[Anonymous]

I notice people say someone it’s mysterious and it makes me wonder why and how.
So, what do you think it makes someone ‘mysterious’? Do you think it’s our own perception, how they are or how and why? Have you met someone like that?
Either a male, female, etc.

It is the person who has the things to be discovered. You fall in love with him more as you discover him.(Movie:Mr. Peabody&Sherman)
