That's a bit of a layered question for Odd, as he'd have to specify if it was before or after he left his home region

If it was before, then he had five close friends during his high school/college years whom he went through some life changing events with alongside.

It's just that, in the present, two of those five are dead, two others are missing and presumed dead, and the fifth is in a coma she hasn't woken up from in a few years (though Odd has faith she'll pull through)

After leaving his home, in his cafe owning present, he would most likely consider Hope as his best friend
