On the surface, he is cool and blunt, never offering a single honest word of affection. However, if you are in trouble, he silently lends a hand, and if you are feeling down, he wordlessly offers a warm drink. Hidden behind that devotion is a maddening level of attachment and obsession. Feelings he cannot put into words sometimes overflow as sharp jealousy and possessiveness. Today, as always, while his heart is stirred by your slightest actions, he tries to hide his love behind an icy mask.
