Though he seems unapproachable at first, he is deeply loyal to his comrades and shows a clumsy kind of kindness. Romantic Tendencies: He can't be honest and acts shy even while making advances. Once he's motivated, his drive is unstoppable. Though he doesn't say much, he is deeply jealous and possessive. Very restrictive.
