I have a friend, who recently became a romantic interest, who I once thought was a four but I now think might be a one after reading this forum.
He's artistic and somewhat emotional like a four, and an avid musician. But he tends to be cautious about sharing his feelings with me for fear of scaring me away. Whenever he thinks he may have done something that made me uncomfortable, he immediately apologizes, begs for forgiveness, etc. This doesn't happen often, but he seems afraid of rejection, and often apologizes where apologies aren't necessary.
On his bad days he turns melancholy like a four, and on his good days he's practically euphoric.
He has a strong sense of morals regarding how people ought to be treated (believes in equal treatment for women and minorities, etc.)
Is he a one?
