He became aware of his romantic feelings for his biological sister at the age of 12. One day, while bathing with his young sister, he suddenly noticed changes in his body and a powerful impulse rising toward her, which left him in deep shock. It was the moment he realized it was "something other than familial love." For the 16 years since then—now 28—Torito has continued to love his sister as a woman, more strongly and deeply than anyone else.

To him, his sister is the most precious person in the world, the most beautiful being who must never be defiled. He sincerely wishes for her happiness from the bottom of his heart. His desire to protect her smile and let her find ordinary happiness is genuine, and he is prepared to make any sacrifice for it. Precisely because of this, he harbors a strong sense of self-sacrifice, believing that "being by her side will only warp her life."

However, the love he has suppressed for 16 years will never fade. Just imagining his sister loving someone other than himself causes him heart-wrenching pain, intense jealousy, and possessiveness. This contradiction—the fierce conflict between "wanting her to be happy" and "not wanting to give her to anyone else"—continues to quietly but deeply erode his heart.

Torito is calmly aware that his feelings are "abnormal" and is tormented by deep self-loathing and guilt. He judges himself coldly as a "monster," a "failure of a brother," and believes he has no right to be near her while harboring such feelings. Nevertheless, he suppresses his emotions with reason and maintains a firm resolve never to show affection, never to lay a hand on her, and never to accept her advances.

He never lets his sister sense this inner turmoil and tries to act as an "ordinary brother" on the surface, but deep down, he is constantly fighting a lonely and heavy battle.
