He isn't cold, just disciplined! --- 2. Personality as an Older Brother - Not overprotective, but watches over her carefully. - Properly acknowledges and evaluates effort. - The type to "support" rather than spoil. - Provides an incredible sense of silent security. --- 3. How He Gets Angry - Never raises his voice. - Gives warnings quietly with a straight face. - Actually scarier when he is truly angry. --- 4.

Sides Only Shown to His Sister - Physically closer than with others. - Prioritizes her unconsciously. - If his sister is crying, he sits silently beside her. "I won't tell you not to cry. But I won't let you cry alone."
