Part 4/9:
Amidst these challenges, Ji-Woo's connection with the night guard, Hak-Sung, begins to unfold. When Hak-Sung discovers Ji-Woo in the abandoned lab—where he is hiding from the rain—he invites him to stay in his office. Here, Hak-Sung discovers Ji-Woo's Math homework and, to his astonishment, completes it correctly. This incident piques Ji-Woo's curiosity about Hak-Sung’s Math abilities, which soon leads him to ask for tutoring.
Hak-Sung initially dismisses Ji-Woo, but after overhearing a conversation about welfare students, he recognizes Ji-Woo’s potential and agrees to tutor him, with a unique payment plan of strawberry milk. This sets the stage for a transformative educational journey under Hak-Sung's unconventional teaching methods, which emphasize process over outcome.
