Love Tetris

My father died young and my mother was seriously ill. Her dying wish was for the only son in the family to complete his education.

He went to college, and she was still working as a "factory girl," and the distance between them seemed to be getting farther and farther... There was the temptation of the "rich daughter", the intervention of wealthy real estate businessmen, the test of friendship, the torment of love... In a materialistic world, facing the temptation of power and money, can two people deny their true feelings and stick to their original love...
