I'm Not Your Brother

A rebellious heir harbors deep resentment toward his stepbrother, a seemingly obedient young man who moves into his household after their parents marry. The two clash constantly at home and at school, each judging the other harshly. Beneath all the rivalry and prejudice, however, they slowly discover a sincerity neither expected. When the heir's father falls gravely ill and needs a kidney, the stepbrother steps forward to give one, winning the trust and affection of the whole family.
